Fact-checked by Barrister Garn Tuntasatityanond, Barrister-at-Law and licensed Thai lawyer (Thailand Lawyer Licence No. 3417/2553), on 11 October 2026.

The reported case of Chinese investigative journalist Bai Zhaodong illustrates why two questions must be kept separate:

1. Is his continued detention lawful under the legal basis currently relied upon?
2. May Thailand ultimately extradite or otherwise return him to China?

A ruling that detention is lawful does not by itself decide the extradition case. Equally, UNHCR recognition and acceptance for resettlement in a third country are highly relevant facts, but they do not automatically cancel Thai immigration or extradition procedures.

What has been reported about the Bai Zhaodong case?

According to reports by Reporters Without Borders (RSF) and other media, Bai Zhaodong is a 56-year-old former Chinese investigative journalist whose work addressed corruption and abuse of power. The reports state that he left China in 2023, arrived in Thailand in 2024, was recognised as a refugee by UNHCR and was accepted for resettlement by a third country.

Those reports further state that he was detained by Thai immigration authorities in January 2026 while arrangements were being made for departure to the third country, but that two scheduled departures—in February and June 2026—did not proceed. China confirmed in July 2026 that it had requested his extradition.

On 8 October 2026, Thai authorities reportedly brought him before the Criminal Court as the extradition process began. On 9 October 2026, the Bangkok South Criminal Court reportedly dismissed a petition challenging his detention. A report by Hey Thailand News states that the court treated the immigration detention as lawful under Section 54, third paragraph, while the extradition request was being processed.

Important qualification: this article relies on public reports for the case timeline and the reported reasoning of the orders dated 8–9 October 2026. The complete court orders, the Immigration Bureau’s return order, China’s extradition papers and the resettlement documents should be reviewed before giving a case-specific opinion. Bai has not been finally adjudged extraditable merely because proceedings have begun.

Detention and extradition are different legal questions

Immigration detention: the paragraph of Section 54 matters

Section 54 of the Immigration Act B.E. 2522 (1979), in the current OCS text, deals with a foreign national who entered or remains in Thailand without permission, or whose permission has expired or been revoked.

The section creates legally distinct stages:

• Investigation before a return decision: Section 54, second paragraph, applies Sections 19 and 20 by analogy. Section 20 imposes time and court-application requirements where detention must continue beyond the statutory periods.
• Waiting after a return order has been made: Section 54, third paragraph, allows the competent officer either to permit residence at a specified place subject to reporting and security conditions, or to detain the person for as long as necessary while awaiting return.

The words “as long as necessary” should not be paraphrased as an unlimited power immune from judicial examination. The decisive documents are the return order, the legal status of the person at each stage, the stated purpose of continued detention and whether the detention remains connected to that lawful purpose.

Supreme Court Judgment No. 1181/2564: why the detention basis must be identified precisely

Supreme Court Judgment No. 1181/2564 is the most useful Thai authority for understanding the distinction between the second and third paragraphs of Section 54.

In that case, the foreign national denied the allegations and the investigation was unfinished. The Supreme Court treated the situation as an investigation for return under Section 54, second paragraph—not detention after a return order under the third paragraph. Sections 19 and 20 therefore applied by analogy. Because the person was kept in a police-station detention room considered unsuitable and the immigration officer did not seek court authority when detention exceeded the statutory period, the detention was unlawful and relief under Section 90 was available.

This judgment does not establish that every person held at an Immigration Detention Center must be released after seven days. It establishes that the court must first identify the correct statutory stage and then test compliance with the requirements governing that stage.

What does a Section 90 petition do?

Section 90 of Thailand’s Criminal Procedure Code, in the current OCS text, permits the detained person, the public prosecutor, an inquiry officer, the prison commander or warden, a spouse or relative, or another person acting for the detainee’s benefit to ask the competent criminal court for release from unlawful custody.

The court conducts an urgent ex parte inquiry. If the custodian cannot satisfy the court that the detention is lawful, the court must order release. The remedy is directed at detention that continues at the time of the petition. Supreme Court Judgment No. 1368/2550 illustrates that once the applicant has already been released, the Section 90 issue may no longer require determination.

A dismissal of a Section 90 petition means the particular detention challenge did not succeed on the basis and evidence then before the court. It should not be reported as a final decision that extradition is lawful.

Can Thailand extradite a UNHCR-recognised refugee?

UNHCR recognition does not, by itself, remove the jurisdiction of Thai authorities or courts under Thai law. Thailand is not a party to the 1951 Refugee Convention, and a UNHCR document does not automatically replace a Thai visa, cancel an immigration order or terminate an extradition proceeding.

However, refugee recognition is not legally irrelevant. It may provide important evidence about the individual’s history, the reasons for flight, the credibility of the feared harm and the availability of safe resettlement in a third country. Those facts may be central when Thai authorities and courts assess statutory bars and protection against return.

The Extradition Act: beginning the case is not the same as approving extradition

Thailand’s Extradition Act B.E. 2551 (2008), in the current OCS text, establishes both executive and judicial steps.

• Section 9: extradition may proceed for an extraditable criminal offence that is not barred under Thai law and is not a political or purely military offence, subject to the section’s qualifications.
• Section 14: the Central Authority reviews the request and, when the statutory conditions are met, directs a public prosecutor to apply to the court for an arrest warrant and further proceedings.
• Section 18: once the requested person has been arrested, the public prosecutor must bring the matter before the court without delay. The court ordinarily orders detention during the proceedings, and an application for temporary release remains possible under the statutory framework.

The requesting state’s description of an allegation—such as extortion or an economic offence—is not necessarily conclusive. The defence may need to examine the conduct alleged, the evidence, the surrounding political context, the identity of the complainant, the chronology of the journalist’s reporting and whether the ordinary-crime label masks a political purpose. That analysis requires the actual extradition request and supporting evidence; it should not be decided from a press release alone.

Section 13: Thailand’s domestic non-refoulement rule applies to extradition

The strongest current statutory safeguard is Section 13 of the Prevention and Suppression of Torture and Enforced Disappearance Act B.E. 2565 (2022), in the current OCS text.

Section 13 prohibits a state agency or official from expelling, returning or extraditing a person to another state where there are reasonable grounds to believe that the person would be in danger of torture, cruel, inhuman or degrading treatment, or enforced disappearance.

This provision expressly covers extradition. It therefore cannot be answered merely by saying that Thailand is not a party to the Refugee Convention. The practical dispute will concern the quality and individualisation of the risk evidence: past charges and detention, journalism records, threats, medical vulnerability, country-condition material, treatment of similarly situated journalists and any reliable assurances offered by the requesting state.

Why Supreme Court Judgment No. 873/2523 must be used cautiously

Supreme Court Judgment No. 873/2523 is sometimes cited for the proposition that a refugee-related argument did not override Thai immigration law. But the case was decided under the Immigration Act B.E. 2493 (1950), not the current Act, and decades before Section 13 created an express domestic prohibition covering return and extradition.

It may be useful as historical context, but it should not be treated as a complete answer to a 2026 case governed by later legislation.

Documents the legal team should obtain immediately

1. The complete 9 October 2026 order: confirm the court’s actual findings, statutory basis and evidentiary record.
2. The Immigration Bureau return order and proof of service: determine whether Section 54, third paragraph, was legally engaged and when.
3. The extradition request and supporting papers: identify the precise charges, conduct, dates, arrest warrant, evidence and translations.
4. UNHCR and third-country resettlement documents: establish recognition, the destination state’s acceptance and the cancelled travel arrangements.
5. Individual risk evidence: collect the journalist’s work history, prior charges, threats, medical records, expert material and current country information.
6. The detention timeline: map each transfer, legal basis, order, application and hearing to test whether authority changed at any point.

Frequently asked questions

Does UNHCR refugee status automatically stop extradition from Thailand?

No. It does not automatically end Thai proceedings. It can, however, be important evidence when the court and authorities assess the alleged political context and the risk prohibited by Section 13.

If a Section 90 petition is dismissed, has the court approved extradition?

No. A Section 90 petition tests the lawfulness of current custody. The extradition court must separately decide whether the statutory conditions for extradition are met.

Can immigration authorities detain someone indefinitely under Section 54?

Section 54, third paragraph, permits detention for as long as necessary after a return order while return is pending. But the actual legal stage, existence of the order, purpose and continuing necessity must be examined. The phrase should not be reduced to an unreviewable unlimited power.

Can Thailand extradite a person who may face torture?

Section 13 prohibits a Thai state agency or official from extraditing a person where there are reasonable grounds to believe that the person would face torture, cruel or inhuman treatment, degrading treatment or enforced disappearance.

Is an ordinary criminal charge always outside the political-offence exception?

No. The legal character of the alleged conduct and the surrounding facts must be assessed. The court should examine the actual request and evidence rather than rely only on the title of the foreign charge.

Can the requested person seek bail during extradition proceedings?

An application for temporary release may be made. Under Section 18 of the Extradition Act, the court considers the application within the extradition framework and hears any objection from the public prosecutor.

This article provides general legal information based on law and public reports available as of 11 October 2026. It is not a substitute for reviewing the complete court orders, immigration file, extradition request and individual protection evidence.

Thailand’s Prime Minister’s Office Regulation on Deportation B.E. 2569 (2026) took effect on 28 August 2026. It does not create deportation power for the first time and does not mean that every foreign national who is fined will automatically be deported. Its principal significance is procedural: it sets out how authorities report cases, refer information to the Minister of Interior and arrange the removal of a person who is subject to a deportation order.

For a foreign national facing criminal proceedings, the practical lesson is important. Completing a sentence, paying a fine or receiving a suspended sentence may conclude one part of the criminal case, but it does not necessarily determine the separate question of whether the person may remain in Thailand.

What changed on 28 August 2026?

The Regulation was signed on 26 August 2026, published in the Royal Gazette on 27 August 2026 and, under Clause 2, came into force on the following day. The official three-page text is available in the Royal Gazette — Prime Minister’s Office Regulation on Deportation B.E. 2569 (2026). The instrument should also be searched by its exact Thai title, “ระเบียบสำนักนายกรัฐมนตรี ว่าด้วยการเนรเทศ พ.ศ. 2569,” in the Office of the Council of State law database.

The Regulation clarifies the administrative chain between courts, prisons, immigration-related authorities and the Ministry of Interior. Among other matters, it addresses:

• reporting conduct considered contrary to public order, good morals or public welfare;
• six groups of offences or forms of participation considered under Clause 5;
• notification before a prisoner is released;
• notification where a final judgment imposes a fine or a suspended term of imprisonment; and
• arrangements for removal, including a formal request by another country or an international organisation in specified circumstances.

What did not change?

Thailand already had a statutory power to deport foreign nationals. Section 5 of the Deportation Act B.E. 2499 (1956) authorises the Minister to order the deportation of a foreign national where this is necessary for public order or good morals, for a period the Minister considers appropriate. It also permits the Minister to revoke the order if circumstances change. The section contains a specific exclusion for a person who previously acquired Thai nationality by birth. See the current Deportation Act in the Office of the Council of State database, Section 5.

The 2026 Regulation therefore primarily provides a clearer operating procedure for using an existing statutory power. It should not be described as an automatic-deportation law.

Clause 4: public-order conduct is a separate ground for review

Clause 4 addresses a foreign national whose behaviour or circumstances are considered contrary to public order, good morals or public welfare. It provides for the Permanent Secretary for Interior, or an authorised person, to report the matter to the Minister for a deportation order. The wording also extends to a foreign national alleged to have instigated or supported that conduct. See Clause 4 of the 2026 Regulation in the Royal Gazette and the OCS database search for the current instrument.

This clause should not be confused with the six categories in Clause 5. A lawyer assessing risk should ask both whether the case falls within Clause 5 and whether the authorities are relying separately on public-order circumstances under Clause 4.

An accusation, complaint or news report does not prove that the alleged conduct occurred or that a deportation order is lawful. The evidence, reasons, decision-maker and statutory basis must be examined in the individual case.

Clause 5: the six groups identified by the Regulation

Clause 5 concerns specified offences and forms of participation. In summary, the listed groups cover:

1. unlawful entry into or stay in Thailand under immigration law;
2. unlawful work under the law governing foreign workers;
3. unlawful business activity under the Foreign Business Act framework;
4. forgery of an official document or use of a forged official document;
5. an offence for which the law prescribes imprisonment of five years or more; and
6. participation as a principal, instigator or supporter in the preceding conduct.

The fifth category refers to the punishment prescribed for the offence; it should not be paraphrased as requiring the court to impose an actual five-year sentence in every case. The sixth category also requires analysis of the person’s real role and the elements of criminal participation. Mere contact with an accused person is not enough by itself. Review Clause 5 in the official Royal Gazette text and search the exact title in the OCS law database.

Why the 15-day prison notification matters

Where a person within Clause 5 is serving a sentence, the Regulation requires the Department of Corrections to send the relevant information before release, with the source text specifying a period of not less than 15 days. This enables the deportation process to be prepared before the person completes the prison sentence.

This 15-day period is an inter-agency notification period. It is not the deadline for the foreign national to appeal a deportation order. A family or employer should not assume that release from prison means the person will immediately be free to return home, resume work or travel. The existence of any immigration detention, referral or deportation order must be checked separately.

A fine or suspended sentence does not mean automatic deportation

The final paragraph of Clause 5 addresses a final judgment imposing imprisonment with suspension of punishment, or a fine, and provides for the Office of the Judiciary to notify the designated Ministry of Interior official for urgent consideration. See the official text of Clause 5.

Three distinctions are essential:

1. Finality of the judgment: paying money does not by itself establish that every procedural stage of the case has ended.
2. Notification: an agency’s transmission of information is not itself a deportation order.
3. Scope: the final paragraph must be read with the listed categories and the legal basis relied upon; it should not be treated as covering every ticket or administrative payment.

Accordingly, paying a court-imposed fine is not a guarantee that no deportation review will follow, but neither is every fine an automatic route to deportation.

International obligations remain relevant

Clause 6 requires a deportation decision to take account of applicable laws, regulations, Cabinet resolutions and Thailand’s international obligations. Clause 8 provides a procedure under which another country or an international organisation may make a request through diplomatic channels for transfer to the requesting country or a third country in specified circumstances, subject to the prescribed conditions, written consent and time limits. See Clauses 6–8 of the 2026 Regulation.

Separately, Section 13 of the Prevention and Suppression of Torture and Enforced Disappearance Act B.E. 2565 (2022) prohibits expelling, returning or extraditing a person where there are substantial grounds for believing that the person would be in danger of torture, cruel, inhuman or degrading treatment, or enforced disappearance as specified by the section. See the current Act in the OCS database, Section 13.

A third-country transfer is therefore not a general right to choose a destination. The request, consent, timing, expenses, acceptance by the destination and non-refoulement obligations must all be examined.

The critical appeal periods: seven days and 15 days

Sections 7 and 8 of the Deportation Act establish two different time periods:

• Seven days from learning of the deportation order: Section 8 permits the person to appeal to the Prime Minister for revocation of the order or for relief from removal.
• Fifteen days from notification of the order: Section 7 prohibits removal before that period expires. If an appeal is lodged under Section 8, removal must be stayed until the Prime Minister decides it.

These are verified in the OCS consolidated Deportation Act, Sections 7 and 8. They must not be confused with the separate 15-day prison notification described above.

Do not confuse deportation with revocation of permission to stay

A notice described informally as a “deportation” document may in fact be based on a different law. For example, Section 36 of the Immigration Act B.E. 2522 (1979) allows the Director-General of the Immigration Bureau or the Immigration Commission to revoke temporary permission to stay where circumstances warrant. If the Director-General makes the order, the foreign national may appeal to the Immigration Commission within 48 hours from learning of the order, subject to the statutory procedure. See the OCS consolidated Immigration Act, Section 36.

By contrast, an appeal against a Deportation Act order follows Section 8 of that Act. The label used in conversation is not decisive. Counsel should immediately identify the document, issuing authority, legal provision and recorded time of service.

Can a person return to Thailand after the stated period?

The Regulation permits a deportation order to specify a period during which the person may not re-enter Thailand; it does not set one universal period for every case. The actual order must be read.

In addition, Section 12(11) of the Immigration Act treats a person who has been deported by the Thai Government, or by another government in specified circumstances, as prohibited from entering, subject to the section’s case-specific ministerial exception. See the OCS Immigration Act, Section 12(11).

The correct analysis therefore asks two questions: has the period stated in the deportation order ended, and does another immigration-law restriction still apply? Expiry of one period should not be presented as a guarantee of re-entry.

What should a foreign national do after receiving an order?

1. Keep the complete order and every attachment. Record the exact date and time it was received or learned of.
2. Identify the legal basis immediately. Determine whether the document is issued under the Deportation Act, the Immigration Act or another law.
3. Protect the shortest deadline first. A seven-day or 48-hour period can be lost while parties wait for non-essential documents.
4. Obtain the criminal case record. Collect the charge, judgment, proof of finality, fine receipt and release documents.
5. Prepare relevant personal evidence. Family responsibilities, genuine care of a Thai spouse or child, health issues, lawful work and business ties may be relevant, but they are not an automatic defence.
6. Check for detention and travel arrangements. Release from the criminal process does not necessarily end immigration custody or removal arrangements.

For more detail on the separate immigration process, see our article on marriage-visa revocation and the 48-hour appeal in Thailand.

What should employers do?

Employers should confirm that the employee’s actual activities match the permission to stay and work, and should designate a responsible person for urgent government notices. If a foreign employee is arrested, prosecuted or receives an official document, the employer should ensure that the document reaches the responsible lawyer promptly rather than assuming that payment of a fine ends every issue.

Records should include the passport, current permission to stay, work authorisation, charge documents, judgment, receipts, release documents and proof of service of any order. Sensitive documents should be transmitted only through a secure agreed channel.

Frequently asked questions

Is the 2026 Regulation a new Deportation Act?

No. It is a Prime Minister’s Office regulation governing procedure. The principal statutory power already existed under the Deportation Act B.E. 2499 (1956). The two instruments must be read together.

Does every foreign national who pays a fine now face automatic deportation?

No. Notification and consideration are not the same as a deportation order. The nature of the offence, final judgment, relevant category under the Regulation, evidence and legal basis must be examined. Paying a fine also does not guarantee that no separate deportation process will follow.

Does the offence always require an actual five-year prison sentence?

No. The relevant Clause 5 category refers to an offence for which the law prescribes imprisonment of five years or more. The statutory maximum must be checked; it is not limited to the sentence ultimately imposed after mitigation.

Is the appeal period 15 days?

Not under Section 8 of the Deportation Act. That appeal must be filed within seven days from learning of the order. The Act’s 15-day period restricts removal after notification, while the Regulation’s separate 15-day period concerns advance prison notification.

Can a person always choose to go to a third country?

No. Clause 8 requires a formal diplomatic request and other conditions, including written consent and arrangements concerning acceptance and expenses. Other Thai laws and non-refoulement obligations may also apply.

When should legal advice be obtained?

Risk should be assessed while the criminal case is still being managed. If an order has already been received, legal advice should be obtained immediately because the applicable deadline may run from the precise date and time of knowledge or service.

Conclusion

The 2026 Regulation makes the deportation workflow more explicit, but it does not turn every fine, suspended sentence or accusation into automatic removal. The decisive task is to identify the legal instrument being used, the authority that issued the document, the evidence relied upon and the correct deadline.

This is often informally called a “litigation visa” or “court case visa.” Technically, however, it is not a separate visa category. It is an extension of the applicant’s existing permission to stay under the Immigration Bureau’s rules.

Being involved in a case does not automatically extend immigration status. The application must be supported by evidence, filed before the current permission expires, and approved by an immigration officer.

Who May Apply for an Extension Based on Legal Proceedings?

Clause 2.26 of Royal Thai Police Order No. 327/2557 covers a foreign national who can prove involvement in litigation or proceedings connected with a case as one of the following:

• an accuser or complainant;
• an injured person or victim;
• an alleged offender or suspect;
• a plaintiff;
• a defendant; or
• a witness.

The rule can therefore assist more than criminal defendants. Depending on the facts and supporting documents, it may also apply to victims, witnesses, and parties to civil or criminal proceedings.

The applicant must also have no circumstances indicating that the legal process is being used merely to prolong their stay in Thailand.

How Long Can the Extension Be Granted?

Immigration considers the necessity arising from the case. If approved, the extension may be granted for no more than 90 days at a time.

The full 90 days is not guaranteed. The officer may consider the next police or court appointment, the current stage of proceedings, the applicant’s immigration record, and the documents provided. If the case continues beyond the approved period, a fresh application may be required before the new expiry date.

The existence of an ongoing case does not create an unlimited right to remain until final judgment. Each extension remains subject to official approval.

Core Documents for a Court Case Visa Extension

The Immigration Bureau’s public guidance identifies the following core documents:

1. TM.7 application form for an extension of temporary stay;
2. one recent photograph measuring 4 x 6 centimetres;
3. the application fee of THB 1,900;
4. the applicant’s passport and signed copies of the relevant passport pages; and
5. a certificate from the inquiry official handling the case, or another official letter or document confirming the applicant’s involvement in the litigation or related proceedings.

Depending on the case and the responsible immigration office, it is prudent to prepare additional supporting material, including:

• a court appointment notice or record of proceedings;
• the complaint, charge, indictment, or statement of claim, where appropriate;
• documents showing the case number, court, parties, and next appointment;
• bail or temporary-release documents, if applicable;
• proof of the applicant’s current address and the accommodation notification record, where requested;
• a Thai translation of foreign-language documents; and
• a short cover letter explaining why the applicant must remain in Thailand and the period requested.

Requirements can vary with the applicant’s role and the local office’s review. Confirm the current checklist with the immigration office responsible for the applicant’s residence before filing.

Step-by-Step Application Process

1. Check the Current Permission-to-Stay Expiry Date

Do not rely solely on the visa sticker. Check the most recent immigration stamp or other official record showing the date through which the applicant is permitted to stay.

Begin preparing the application well before that date. A pending court case, police investigation, or request for a supporting letter does not stop the immigration clock.

2. Obtain Official Confirmation of the Case

Request a certificate or supporting letter from the inquiry official or obtain an official court document confirming the applicant’s connection with the case. The document should, where possible, identify:

• the applicant and their role in the case;
• the case or reference number;
• the authority handling the matter;
• the current stage of proceedings;
• the next required appointment; and
• why the applicant’s continued presence is necessary.

A lawyer’s letter alone may help explain the application but may not replace the official evidence required by Immigration.

3. Deal With Any Passport Restriction

If the passport has been deposited with a court or authority as part of bail or another order, do not assume it can simply be collected. A lawyer may need to file a request asking for temporary access to the passport for the immigration application.

The request should explain the immigration deadline, the purpose and period of use, and when the passport will be returned. Approval remains a matter for the court or authority holding it.

4. Prepare the TM.7 Package

Complete the form accurately and ensure that names, passport details, entry information, address, case information, and requested period are consistent across all documents. Bring originals for inspection and signed copies where required.

5. Apply at the Responsible Immigration Office

The applicant should contact the immigration checkpoint or office responsible for the area in which they reside. The Immigration Bureau’s guidance states that the foreign national must apply in person.

The officer may request clarification, additional documents, or further confirmation from the police, court, or another government authority. Filing a complete application does not guarantee approval.

6. Check the New Stamp and Calendar the Next Deadline

After approval, check the permitted-until date before leaving the counter. Keep a copy of the application, receipt, supporting letter, and new stamp. Calendar the next immigration deadline separately from every police and court appointment.

Overstay and Blacklisting Risks

Do not allow the permission to stay to expire while waiting for case documents. Involvement in litigation does not excuse overstay automatically.

Overstay is an immigration violation. Official Immigration Bureau guidance states that the usual fine is THB 500 per day, capped at THB 20,000. More importantly, overstay can expose the foreign national to arrest, removal, and a ban on returning to Thailand. The blacklisting period depends on the length of overstay and whether the person leaves voluntarily or is apprehended.

A common and dangerous assumption is that a foreign national can overstay, pay the fine, and then obtain a litigation extension as a matter of course. That is not a safe legal strategy. Once lawful permission has expired, the available procedure depends on the individual’s immigration and case status and requires urgent professional assessment.

Does the Extension Replace 90-Day Reporting?

No. An extension of stay and the address-reporting obligation are separate matters. A foreign national staying in Thailand for more than 90 consecutive days must comply with the applicable 90-day reporting rules unless an exemption applies.

The accommodation notification made by a householder, owner, or hotel and the foreign national’s own 90-day report are also separate requirements.

Can the Applicant Leave Thailand During the Case?

Before travelling, check both immigration status and the case file.

Leaving Thailand without the required re-entry permission may cause the existing permission to stay to end. Separately, bail conditions, a court order, a passport restriction, or an immigration watchlist may prevent departure or require prior approval. A re-entry permit does not override a court order or bail condition.

Frequently Asked Questions

Is every foreign defendant eligible for a litigation extension?

No. Eligibility depends on proof of genuine involvement in the proceedings, the necessity of remaining in Thailand, the absence of conduct suggesting delay, valid immigration status, and the officer’s assessment. The fact that a person is named in a case is not automatic approval.

Can a victim or witness apply?

Potentially, yes. The applicable rule expressly includes an accuser, injured person, and witness, as well as a suspect, plaintiff, and defendant. Official documentation should explain why that person’s continued presence is needed.

Is the extension always 90 days?

No. Ninety days is the maximum for each approval under this ground. Immigration may grant a shorter period based on the needs and timetable of the case.

What if the passport is held by the court?

A request may need to be filed with the court or authority holding the passport. The applicant should not wait until the final days of lawful stay because the request and immigration filing may require time.

Can an overstay be fixed simply by paying a fine?

No. Payment of a fine does not by itself restore lawful immigration status or guarantee an extension. Overstay can also result in arrest, removal, and a re-entry ban. Obtain urgent case-specific advice.

Practical Advice From a Thai Litigation Team

Foreign nationals involved in Thai proceedings should manage the court calendar and immigration calendar as two separate but connected workstreams. The safest approach is to verify the immigration deadline early, obtain official case confirmation, resolve any passport restrictions, and file a complete application before the current permission expires.
