Do I need to cancel my Education visa before switching to a TR visa for a work permit in Thailand?

@Ryan *****

i'd say whether you 'want' to cancel your current extension or not doesn't really factor into the equation. The way it works is to officially cancel an extension you get a letter from the school stating you're stopping studying and then you go to the immigration office. They'll cancel the extension you're on and give you a stamp saying you can stay until the date on the termination of study letter.

Just leaving the country doesn't cancel the extension officially, and even though you will stamp out, get a new tourist visa, come back into the country when you go to get the in country Non-B and then the extension after that they'll see you failed to correctly cancel your ED visa extension and fine you for it.

Now you have the correct way it should be done, I leave it to you to decide what you're gonna do.

Good Luck

If you keep extending it, it sounds like you have an Extension of Stay, not a visa. You can not get a Work Permit if you have a Tourist Visa. Your employer should apply for the Work Permit using the Work Permit application method 3 and if application is done you take the documents from the ministry of labor and the documents from your employer to apply for the Non Immigrant B visa. Before you leave you cancel your current Extension of Stay based on study at your local Immigration Office.

Yes. You are required to cancel your ed visa before you leave. Please speak to your school and get them to prepare the documents for you to visit the immigration.
