I think he is making more harder than it needs to be, and that can stress out his fiancee, being that she is in school, and I'm sure paying her own bills at home.
what I was trying to get across to him is that, no matter how he arrives, not only will they have to meet the requirements of USCIS, but also maintain a living.
being that they will be just starting this process.. it can destroy the relationship if he doesn't be careful
