What happens to my Non-B Visa and work permit if my teaching contract is not extended?

Why wait till tomorrow to answer your question.

If the school does not give you a new contract, you have to cancel the Work Permit and the Extension of Stay with last date 31 March 2020. You can do this in advance, so you have time to make travel plans to leave Thailand that day. if you can not leave that day you can apply for a new Extension of Stay, it will be NOT approved and you get 7 days to leave the country.

If you like to come back to Thailand you have to organize another visa.

Talk to your school, tell them that you need confirmation on your next contract + paperwork from them to extend your work permit + extension for another year.

It should be so easy and straightforward but some schools aren’t very organized when it comes to paperwork for foreigners, especially if they aren’t used to foreigners on “B” extensions continuing at the school for more than 1 year.

Also FYI, you’ll need to do your tax return before applying for your next work permit extension (but the school should handle the rest of your paperwork)

Start looking for another teaching job ASAP. Take initiative.

Are you now on extension of stay?

What does your contract with school say....or are you contracted thru Agency?
