Visa extension
Tourist visa extension in Koh Samui
30 extra days on your stamp, with a file prepared in advance so one visit to Maenam is enough.
A tourist visa extension in Koh Samui adds 30 days to a tourist visa or visa-exempt entry. It is applied for at the Samui Immigration Office in Maenam using form TM7, with an official government fee of 1,900 THB, normally during the last week of the current stay.
Who can extend
Most travellers on a tourist visa or a visa-exempt entry can obtain one 30-day extension at the local office. Certain entries (some border stamps, special exemptions) follow different rules — send us a photo of your stamp on WhatsApp and we confirm your options within hours.
Documents you need
The Samui office expects a complete file:
- TM7 form, completed and signed
- Passport + signed copies (photo page, visa/entry stamp, arrival record)
- One 4×6 cm photo
- 1,900 THB cash
- TM30 address registration (from your hotel or landlord)
How we help
We fill the TM7 for you, verify every copy, check your TM30 status and tell you the best day and time to go. If something is missing — a photo, a TM30 registration — we fix it before you queue, not after a refusal.
Staying on Phangan or Tao? We prepare everything remotely so your ferry trip ends with a single stop in Maenam.

Frequently asked questions
How many times can I extend a tourist entry?
Normally once per entry: +30 days at the local office for 1,900 THB. Further extensions are exceptional and assessed case by case by Immigration.
When should I apply for the extension?
During the final week of your permitted stay. Applying too early can be refused; too late means overstay fines of 500 THB per day.
What happens if I overstay?
Overstay costs 500 THB per day (capped at 20,000 THB) and can lead to re-entry bans for longer periods. If you are already close to the limit, contact us today — solutions shrink with every passing day.
Do I need a TM30 to get an extension?
Yes, the Samui office asks for proof that your address is registered. Hotels usually file it automatically; private landlords often forget. We check this for you before your visit.
