So... Is it a problem to find another school for next year? Only Tourist visa will be more easy than ED. All other options are costly (money and/or time)
ok, as I told already, re-entry permit will help. But what I was trying to say is "to apply for non-b visa after desert and before coming to Thailand". Just another way around =)
Or... Maybe he should just extend his visa exempt for 30 days more, 2 weeks later fly out of the country with all the paperwork for non-b visa, and just apply for non-b visa where he will be staying before flying back to Thailand?
