Want a little longer in Thailand? Some visitors can apply at Thai Immigration for an extension of up to 30 days. Your eligibility depends on how you entered Thailand and the permission to stay stamped in your passport.
Check your entry stamp first. Eligible British and Irish visitors entering under the visa exemption scheme from 15 September 2026 are normally granted up to 30 days on entry. They may request an extension of up to 30 more days, subject to Immigration’s decision. A 30-day entry plus a 30-day extension is up to 60 days, not 90.
Who can request a 30-day extension?
Eligible visitors on a visa-exempt entry may request an extension at Immigration. Holders of a Thai tourist visa may also be able to request an extension, but should check the conditions of their own visa. The officer assesses each application; an extension is not automatic.
Other entry types have different rules. If you entered using a visa on arrival or a long-stay visa, check your specific category before assuming you can add 30 days.
What should you bring?
- Your passport and copies of the pages requested by the immigration office.
- A completed TM.7 extension application form.
- A recent photograph in the size requested by the office.
- Details of your address in Thailand and any supporting accommodation record requested locally.
- The extension application fee, currently commonly THB 1,900; confirm payment details with the office.
Requirements can vary by office and circumstances. Ask your local Immigration office if it wants additional documents, such as evidence relating to your accommodation or travel plans.
When should you apply?
Apply while your current permission to stay is still valid. Look at the permitted-until date in your passport rather than assuming the date from your flight booking. After the decision, check the new stamp carefully and note your revised departure deadline.
Can you get another 30 days after that?
Do not plan a longer trip on the assumption that repeated tourist extensions will be approved. If you need to spend substantially longer in Thailand, consider the appropriate visa before travel. Leaving and re-entering also creates a new admission decision; it is not a guaranteed way to extend a stay.
