What should I do about my Non-B visa and work permit cancellation before moving to a new school in Thailand?

To be sure, you should ask the immigration office and the provincial labor office. I can give some advice, but I’m not sure if I’m fully correct. I’m in Chiang Mai province where it usually works in two ways:

1. Your situation is that your current job ends on July 31, but your new job starts on July 1. In this case, you might not need to leave the country to get a new visa. You can continue working with your current Non-B visa. You need to arrange between the old and new workplaces so that your old workplace cancels your visa on June 30. You can apply for cancellation 21 days in advance. You must resign from the old job first, for example, resign on June 15, and your old workplace cancels your work permit on June 16. Then you have enough time for the new school to apply for your new work permit as soon as possible. After that, you use the new work permit to extend your visa before June 30 so you can start working at the new school on July 1 according to your contract.

2. If you have to leave the country, you must have your visa canceled and get a cancellation stamp for your work visa at the old job. You should not let the visa be automatically canceled when leaving the country because your work status will still be active, which will cause problems when you apply for a new visa. You must leave the country on the last day of your visa. The old workplace must cancel your work permit after your last working day. If the old workplace does not notify cancellation within 15 days, they will be fined 20,000 baht.
