Good afternoon.

I'm in Chiang Mai on non immigrant O visa one year retirement.

My wife has a non immigrant O - ED Visa that will expire at the end of October after 3 months.

She is not going to renew it because she is changing school

The new school has the documents ready for her and we made the appointment in Vientiane to ask for a new one. She's flying on the 14th of October

Does she need a document from the former school to cancel the visa? Can she cancel the visa at the airport immigration when boarding the plane, as immigration offices are closed that day?

And what date should this document mention? I couldn't find anything clear about an ED visa cancellation and the delay to leave the Thai territory after cancellation.

Thank you so much for your answers.
