Thailand Visa Extension — 30-Day Extension Inside Thailand
Extend your stay legally at Immigration instead of rushing out of Thailand.
Many travellers and long-stay visitors can add an extra 30 days to their stay by applying for a visa extension at a Thai Immigration Office. VisaTrip helps you prepare documents, choose the right office and avoid common mistakes so your extension is smooth and stress-free.
What is a Thailand Visa Extension?
A Thailand Visa Extension is an extra 30 days (in most tourist cases) added by Immigration to the stay period already stamped in your passport. It is usually done at an Immigration Office inside Thailand, not at the airport.
Common for These Visitors
- Travellers who entered with tourist visa or visa-exempt/visa-free stay and wish to remain longer.
- Visitors who need more time to decide next steps (e.g. convert to Education, Work, Business or Marriage status).
- People who want to avoid the stress of overstay or last-minute border runs.
Key Benefits
- Extra 30 days inside Thailand in many tourist cases.
- More time to plan long-stay options (ED, Work, Business, Marriage, Retirement).
- Often cheaper and simpler than flying out and back for a visa run.
- Better for travellers who are tired, busy or working remotely from Thailand.
Documents for a 30-Day Tourist Visa Extension
This is the most common extension type — for tourists who entered with visa-exempt, visa-free or tourist visa stay.
1. Passport & Entry Details
- Original passport with your current entry stamp or visa.
- Photocopies of passport bio page.
- Copies of current visa and latest entry stamp.
- Departure card / arrival record (if still used at that time).
2. Application & Photos

- Recent passport-sized photograph (as per official size).
- Local address in Thailand (hotel, apartment, guesthouse).

Thailand Visa Extension Process — Step by Step
Visa Extension vs Visa Run — Which Option is Better?
Some travellers are not sure whether to extend inside Thailand or leave and re-enter (visa run). Here is a simple comparison:
| Aspect | 30-Day Extension at Immigration | Visa Run (Exit & Re-Enter) |
|---|---|---|
| Main Idea | Stay inside Thailand and add 30 days at an Immigration office. | Leave Thailand to a neighbouring country and come back with a new entry stamp or visa. |
| Time & Effort | Usually 1 half-day at Immigration (waiting times vary). | Travel time to border or another country + flights, buses, hotels. |
| Cost | Government fee + local transport only. | Transport, hotels, possible new visa fee, food and other trip costs. |
| Risk | As long as documents are correct, lower risk and you stay inside Thailand. | Border rules, airline checks and changing entry policies can create uncertainty. |
| Best For | Travellers who are happy with one extra 30 days and prefer not to move around too much. | People who need a fresh entry for a different plan or who enjoy extra travel anyway. |
| Used With | Tourist stays, visa-exempt entries and sometimes as part of planning for later conversions. | More complex strategies, long-term travellers, or when extensions are not available. |
VisaTrip can calculate whether a simple extension or a visa run is more practical for you based on days left, budget and future plans.
Common Mistakes with Thailand Visa Extensions
Waiting until the last day or after the last day of stay. Overstay fines and stricter questioning can follow.
Expecting a 30-day extension to reset all rules or give a completely new visa type.
Arriving without photocopies, photos, or clear accommodation details, leading to extra trips and delays.
Extending again and again without a clear idea of whether you will convert to a more stable long-term visa.
A quick WhatsApp check with VisaTrip can usually prevent these simple but costly errors.

Frequently Asked Questions — Thailand Visa Extension
How many extra days do I get with a tourist visa extension?
Most standard tourist visa extensions give an extra 30 days of stay inside Thailand, counted from your current last day of stay, not from the date you visit Immigration.
Can I extend more than once?
In some situations, multiple extensions are not allowed or may be viewed less favourably, especially without a clear reason. It depends on your visa type, Immigration office and travel history.
Where do I extend my visa in Thailand?
You usually extend at the Immigration office responsible for the province where you are staying — for example Bangkok Immigration, Chiang Mai Immigration, Phuket Immigration, Pattaya Immigration and so on.
Can I extend at the airport on departure?
Extensions are typically done at Immigration offices, not at airport departure counters. Airports are usually for entry/exit processing, not for full visa extension applications.
What happens if I overstay instead of extending?
Overstaying can lead to fines per day, possible blacklisting in serious cases and more questions next time you enter Thailand. Extension is safer than risking overstay.
Is a 30-day extension better than a visa run?
For many travellers, a 30-day extension is simpler, cheaper and less risky than leaving Thailand and hoping for a new entry. However, some complex long-stay plans may still require visa runs. It depends on your situation.
Can I convert to another visa after extension?
In some cases, yes. Travellers may later move to Education, Business, Work or Marriage structures, provided they meet requirements and Immigration allows conversion at that time.
How early should I apply for an extension?
Most people apply about one week before their last day of stay. Too early or too late can cause practical issues. VisaTrip checks your dates and suggests the best window.
What should I bring for a 30-day tourist extension?
Commonly: your passport, passport photocopies, current visa/stamp copies, a photo, accommodation details and the extension fee. Some offices may also ask for a return or onward ticket.
How can VisaTrip help with my extension?
VisaTrip can review your stamp, confirm eligibility, help you choose the right office, prepare your forms and copies and guide you on timing so that extension day is as smooth as possible.
