Hello all! Does anyone have experience or advice for a Thai citizen to get a Visa to visit USA? I have a friend wanting to come visit, but after hours of research I cannot seen to find any real solid information. Some places say buy airline tickets first before interview to show return flight, others say wait for Visa approval.

It looks like the B2 visit is what they are looking for for tourism visit, but could they take some English classes here and travel as student? Since this can be a costly process, I am hoping some here have some advice about best chances of making this happen.

Thanks in advance!
