Will flying home with a re-entry permit result in a passport page use or just a stamp?

@Gra***

, yep, that visa canceled when you got your extension. In fact you used the visa to get the extension just like the system is designed. It's your extension that lets you stay here

You should have a stamp similar to this and this in your passport, one is the extension and one is the re-entry permit. Your extension is based on education this one is retirement but it's the half page extension stamp that lets you stay here and the half page re-entry permit that lets you back in ;)

If you have a re-entry permit you aren't on ANY visa anymore, you're on an extension you got from the immigration office because that's the only time you buy a re-entry permit.

Still as long as you do have a re-entry permit when you return to thailand you will be stamped in until your current 'permission to stay' stamp expires.

There is no such visa as a Non-B ED :/ It's either an ED visa based on study or a B visa based on employment.

Be that as it may seeing as you have a re-entry permit you will just get the small triangle exit stamp when you leave and a small rectangle entry stamp when you come back.
