Expect the following documents required for your first one year extension of stay based on retirement from a single entry Non-O visa:
1. Your passport and a copy of:
a. The data “picture” page.
b. The most recent visa (if applicable).
c. The most recent entry stamp or extension of stay (if applicable).
d. The departure card (“TM 6”) that should be stapled in the passport.
2. The extension of stay application form (“TM 7”).
3. A copy of the submitted Notification of Residence of Foreigners form ("TM 30”).
4. A letter from the bank showing that 800K THB was deposited in a Thai bank account for two months.
5. An updated bankbook on the day when you apply for the extension of stay based on retirement.
6. A hand drawn map to your residence
7. 1x passport sized (4cm by 6cm) photos.
8. 1,900 THB processing fee.
>PS: also I heard you might need copy of vaccination certificate now ??
No proof of vaccine is required to enter the immigration office.
>Do I also need copy of Landlord ID or passport and copy of rental agreement + TM 30 ??
No, that is not required for a one year extension of stay based on retirement. The landlord ID and rental agreement may be required for a TM30 though.
