How can I extend my stay in Thailand after my ED visa expires on July 18 due to COVID-19?

The letter can say that you will finish your study on specific xx date. Depends on your local immigration office, you may be able to apply for cancellation in advance.

But at most immigration office, they would put covid extension starting on the day of application, not adding to your current stamp, you may want to apply for your covid extension as near to the end 'date' of your stamp as possible.

1. You would take a letter from your school saying you no longer are studying, and cancel your ED visa.

2. ON THE SAME DAY, you would apply for a 60 day extension of stay based on unable to travel due to COVID-19.

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, and ant to use their special 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, 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:

You would be able to stay for an extra 60 days.
