What is the process for cancelling a Non-B Working Visa and applying for a Tourist Visa in Thailand?

If you want an 60 day extension of stay based on unable to travel due to COVID-19, you'll need the following:

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 TM.6 departure card

2. [MAY BE ASKED AT BANGKOK IMMIGRATION] A TM30, filed in the immigration office.

3. The forms (each immigration office may have different forms, and want to use their special forms). For Bangkok Immigration, they are found in the Files section of this group. For other immigration offices, please use their own forms.

4. [NOT ASKED AT BANGKOK IMMIGRATION] A letter from your embassy saying you can not return, OR a print out from your embassy website saying they don’t issue the letters, OR a print out of a letter from the embassy saying they don't issue those 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

You got your wires crossed a bit. You can't get a tourist visa inside thailand, period end of story.

What you are talking about is cancelling your Non-B EXTENSION at the immigration office with documents from your employer and then you would immediately apply for a 60 day covid extension for 1900baht. <- that's the only thing you could do and it's not 90 days it's 60 days.
