What documents are required to extend a non-B visa in Thailand?

@Louise ******

then you can't get an extension on the Non-B you have, 😕

There is no way to extend a Non-B without a work permit

you'd have to leave the country and get a new Non-B at a thai consulate

OR

come back in on a visa exempt entry and apply inside the country for a Non-B at the immigration office

@Tod ********

That's interesting I never knew visa exempt could be changed to a non b in Thailand I thought it was a tourist visa, thanks for the info 👍

@Dave *******

visa exempt or tourist visa can be changed to a 90 day Non-B inside thailand providing you meet the requirements and have enough time left on your current stamp

BUT

many employers cannot meet the more stringent requirements to do that in country conversion <- that's why they would just send people to the thai consulates in nearby countries to get them,

The requirements are not as strict at the consulates
