Short answer: If your Thai visa or work permit is expiring, refused, or already lapsed, act before the date passes. A lawyer can review your situation and documents, explain your legal options, help you prepare and submit a visa extension, change-of-visa or work permit application, and advise you on problems such as overstay, refusal, or revocation. Call for a free first conversation.
What we can help with
- Visa about to expire: reviewing your current permission to stay, explaining which extension or change of visa type may be available to you, and helping you prepare the application.
- Extension refused or delayed: reviewing the reason given and discussing possible next steps.
- Work permit issues: expiry, a change of employer, termination of employment, or a work permit that no longer matches your job.
- Overstay concerns: explaining what an overstay can mean and how to approach it with the authorities, rather than avoiding the problem.
- Document preparation and review: checking forms, translations, and supporting documents before you submit them, and explaining any refusal letters, orders, or notices you have received.
- Guidance before you attend Immigration or labour offices, whether for a new application or about a problem such as an overstay, refusal, or revocation.
- Related matters: such as employment disputes or family situations that affect your visa status.
Visa extension, change of visa and work permit applications
As well as advising on overstay, refusal and revocation, Siam Center Law Group can help you prepare and submit applications for a visa extension, a change of visa type, or a work permit.
What we do:
- Document checklist: we give you a checklist based on your visa category, your purpose of stay and your personal circumstances.
- Document review: we check your forms, translations and supporting documents for gaps or inconsistencies before anything is filed.
- Preparing the file: we help you put together a complete, well-organised application file and support you through submission.
- Guidance before you attend Immigration: we explain what to bring, what to expect on the day, and what you may be asked.
If you entered Thailand without a visa, check the stamp in your passport carefully. Since 15 September 2026, visa-exempt entry for tourism is limited to 30 days for nationals of 60 countries and territories, and the previous 60-day scheme has been cancelled (source: Government Public Relations Department, Revision of Thailand’s Visa Exemption and Visa on Arrival Schemes). If you plan to stay longer, contact us early so we can review which options may apply to you.
Important: every visa, extension and work permit decision is made by the Thai authorities. We cannot guarantee that any application will be approved, and requirements can change without notice.

Frequently asked questions
My visa expires very soon. Is it too late to do anything?
Not necessarily, but time matters. Contact a lawyer as early as possible so your situation can be reviewed before the expiry date. What is possible depends on your visa type and personal circumstances.
I have already overstayed. What should I do?
Do not ignore it. An overstay can have serious consequences, and these depend on the facts of your case. Get legal advice on how to approach the authorities before you take any step.
My employer ended my contract. What happens to my work permit and visa?
A change in employment can affect both your work permit and your permission to stay. Speak to a lawyer promptly so your options can be explained based on your actual documents.
Is the first consultation really free? Can you guarantee my visa?
Yes, the first call is free. However, it is not a promise of any result. No lawyer can guarantee a visa, extension, or work permit. Decisions are made by the Thai authorities.
