What should I do about my expired ED visa preventing my tourist visa extension in Thailand?

You will need a letter from your school and cancel your ed visa. I assume you got a few ed extension. You better do it immediately. Oh you better ask them if you have to fly out of the country and fly back in.

Ask the school for a letter confirming cancel, then go to immigration and show the letter

Do not overstay

Never overstay you’ve already done something that can keep you from obtaining a long stay visa if you do a border bounce you’ll need a company that can get you back alone I really don’t like your chances

We don't know your visa history - so it's just a general advice: Do not overstay!

If your stamp history is not too extensive, I would recommend leaving Thailand for a few days and get in touch with the place where you had your ED visa. Let them know that you need the visa to be cancelled, and that you will come next week to pick up the printed confirmation of the cancellation.

Then you could try to get a visa exempt entry into Thailand ( if your passport is eligible) which should give you 60 days.

However, there's is no guarantee that you will be able to enter Thailand again if the IO doesn't see you as a genuine tourist.

Perhaps it would be better for you to look for a company that does a border bounce. They check in advance if you will be able to get back into Thailand.

You can cancel your ED visa simply calling to your school. I remember i called them and took only 10 seconds on the phone. Hi Pat :))

Leaving the country won't cancel the visa, you need a letter from your school and prepare to pay overstay fine

I had to cancel my ed visa before I left when I had one

I would definitely not go into overstay

You need to cancel that visa in Krabi. Sorry 😔 you are doomed otherwise

TiT.
