Where you apply depends on how you entered Thailand. Visa extensions must be completed in person.

Option 1: visa-exempt entry or visa on arrival

This applies if:

• You entered Thailand without applying for a visa at a Thai embassy or consulate.

When to apply

• You can apply for a 30-day extension up to 30 days before your current stay expires.
• A good time to apply is around 7 days before expiry.
• Do not wait until the final day, as delays or missing documents can cause problems.

Extension fee

• The standard fee for a 30-day extension is 1,900 THB.
• Payment is made at Immigration on the day of application.
• The fee is non-refundable, even if the extension is refused.
• Bring cash in Thai baht to avoid delays.

Documents Required for a 30-Day Extension

You must prepare the following documents before visiting Immigration:

• Original passport, valid and in good condition
• TM7 form – Application for Extension of Temporary Stay (PDF)
• Passport copies, including:
  • Bio (photo) page
  • Current visa or entry stamp page
  • Any previous extension stamps
• One recent passport photo (4 x 6 cm)
• TM30 confirmation showing your registered address in Thailand
• Your Thailand Digital Arrival Card (TDAC)

Important preparation tips

• Sign every copy using a blue pen.
• Make sure all copies are clear and readable.
• Keep all documents neatly organised in one folder.

If you are missing copies or photos, photocopy and photo services are available on the 1st floor of IT Square and on the basement floor of Immigration Division 1. Allow extra time if you need to use these services.

What happens at Immigration

Once your queue number is called, you will submit your documents, pay the extension fee, and wait for the officer to process your application. Approval is usually granted on the same day.

Processing times vary depending on how busy the office but usually half a day.

Before you leave Immigration

Before leaving the counter, double-check that you have the correct passport and that the 30-day extension stamp is accurate.

• Your name matches your passport.
• The new expiry date is correct.
• The stamp clearly shows the additional 30 days.

Any errors should be corrected immediately before you leave Immigration.

Overstaying your visa

Staying in Thailand beyond your permitted date without a valid extension can result in fines, deportation and may affect future visa applications.

Always apply for your visa extension before your current stay expires.

Final advice

• Apply before your visa expires.
• Arrive early to reduce waiting time.
• Bring cash and all required documents.
• Ask your hotel or landlord for your TM30 well in advance.
