I have just got my Non-B in Laos and will fly back to swampy on Tuesday.

I had 2 offers, and documents from 2 schools, I was unsure what school I would choose, so I just done the Non-B using one of the schools and thought I'd be able to make my decision once visiting both schools.

There is Thai writing above my new Non-B and a Thai friend has confirmed it's the name of the school.
 

Am I now consigned to that school, or is there still a way I can change to the other school?

Thank you,
James

You will find it difficult to get an extension and a work permit for another school without permission from the school shown on the non-b visa.
