How can I extend my STV visa in Thailand and what documents do I need?

What immigration office will you use? Assuming you did not enter AFTER July 3rd, you can get a 90 day extension of stay based on STV. You can only get an extension of stay at the immigration office where you reside. Officially, you will need the following documents:

1. Your passport and:

- Copy of the picture "Data" page

- Copy of the TM 6 departure card

- Copy of the STV visa

- Copy of your entry stamp

2. The visa application form that you can get at the immigration office. Some immigration offices want their own form

3. Proof that you stayed at the ASQ (Alternative State Quarantine) showing you completed the ASQ

4. The health insurance showing that you meet the qualitifications. It's the same health insurance that you used to enter Thailand.

5. Either a:

- Rental agreement for a condo showing the rental period with the Thai ID owner OR;

- A prepaid hotel booking with the hotel ID number OR;

- Proof of ownership of a condo

6. 2x Passport pictures

7. 1,900 THB for the application fee
