Task
Extend a stay
Apply in Thailand to add days to a tourist exemption, TR, or other eligible stamp.
· checked against official sources below
Who this is for
People already in Thailand whose stamp allows an in-country extension (commonly 30 days for tourism).
Overview
An extension is a new permission, not an automatic extra month. You file TM.7 at a provincial immigration office, pay the fee, and wait for a new stamp. Same-day service is common but not guaranteed. Bring more photographs and photocopies than you think you need. Overstaying while you “plan to extend tomorrow” is still an overstay.
| Item | Amount | Notes |
|---|---|---|
| Tourist / exemption extension (typical) | 1,900 THB | Cash; TM.7 |
How to do it
- 1
Confirm your current stamp can be extended
Not every entry type extends. The office that granted the stamp, and the current notification, control this. - 2
File TM.7 in person
Arrive early. Many offices take a photo and fingerprints on site. Collect the passport the same day if they say so.
Documents
- Passport
- TM.7 form
- One or more passport photographs
- 1,900 THB in cash (typical tourist extension)
- TM.30 receipt if the office requires it
What changed
A typical in-country tourist extension is 30 days on TM.7 at about 1,900 THB. Approval is discretionary.
