Application for non-nationals

Hey, Me and my girlfriend are traveling to Thailand from the 4th of July to the 24th, she is supposed to go on a trip through her university to china on the 8th of august however she has not gotten her visa sorted out yet and she doesn't have a lot of time to get it fixed now. I was wondering if it is possible for her to get it while we're in Thailand? She has invitation documents from the school she will be residing at and all the relevant documents.
