How long can I stay in Thailand under the sandbox program and am I able to extend my stay?

It seems like the poster just wants to stay a few extra weeks, and may not be interested in getting a60 day extension of stay based on unable to travel due to COVID-19. If further information is required, please message a poster and we'll reopen commenting.

Remember too, the OLD (Pre-January 25, 2022) 60 day extension of stay based on unable to travel due to COVID-19 no longer exist. See 3/permalink/8

For information about the NEW 60 day extension of stay based on unable to travel due to COVID-19.

Hmmmm looking at the above photo I would take a wild guess and say you can stay until 14th Feb. With the option to extend to March 16th for 1900b. I would suggest leaving before feb 14th to avoid any expenses occurred by Valentine’s Day.

You entered on a 30 day visa exempt ("ผ"). You can stay for 30 days in Thailand until 14 February 2022. You can get ONE 30 day extension of stay based on tourism at the local immigration office.

After you get the 30 day extension of stay based on tourism, you *MAY* be able to get ONE 60 day extension of stay based on unable to travel due to COVID-19. The last day a person can apply for a 60 day extension of stay based on unable to travel due to COVID-19 is March 25, if my memory serves me right.

You will acquire the extension of stay at the local immigration office. You will need the following documents:

1. The applicant’s passport and a copy of:

a. The data “picture” page.

b. The most recent visa (if applicable).

c. All entry stamps or extension of stay (if applicable) since arrival .

d. The departure card (“TM 6”) that should be stapled in the passport.

2. The extension of stay application form (“TM 7”).

3. [May not be asked at Bangkok Immigration] A copy of the submitted Notification of Residence of Foreigners form ("TM 30”).

4. 2x passport sized (4cm by 6cm) photos. For Bangkok Immigration, only 1 passport size photo is required.

5. 1,900 THB processing fee.

The 60 day extension of stay based on unable to travel due to COVID-19 is optional, and does not need to be issued by the immigration office. If it's granted, consider it as an extra "bonus".
