Can I take Thai language classes on an education visa and later switch to Chulalongkorn University?

Hello my name is andre, i have been planning on moving to thailand for the past couple years and I think it's finally time to take the leap. Would I be able to take six months to a year of thai language classes out in town underneath the education visa and then leave the school once i'm completed with the program to then attend school at chulalong? Im a veteran and would like to use my gi bill. In my head, i would be underneath a student visa, but they would just have to change the details underneath my file.When it came for immigration. Or would they look at it like i'm applying for a second student visa... And start putting up a fuss and start scrutinizing and asking questions, regardless, they'll ask questions. Does anybody here know anyone or anything about the possibilities of approval for this visa strategy.
