I'm assuming you're getting a 60 day extension of stay based on unable to travel due to COVID-19 (HIGHLY recommend over the 60 day extension of stay based on visiting Thai Family).
Different immigration offices have different requirements, but all require the following:
1. Your passport and:
a. a copy of your data ("picture") page
b. a copy of your most recent visa (if you have one)
c. a copy of your most recent stamp
d. a copy of your departure card
2. A TM30, filed in the immigration office.
3. The forms (each immigration office may have different forms)
4. A letter from your embassy saying you can not return, OR a print out from your embassy saying they don’t issue the letters.
5. 2x passport pictures
6. 1,900 THB.
Different immigration offices have different policies. *SOME* may require:
- The ID card of the property owner where you are staying
- Copies of *ALL* stamped pages in your passport
Which immigration office are you using?
