Here's a little more detail. She's on a J-1 visa. She has a flight back to Moscow booked for Sept. 26. She wants to see her family and they are worried about her not filing papers correctly and being stuck here with no rights, etc... They want her to come back to Russia and do the documents from there. I might be wrong but I feel like if she goes home it will take a very long time for her to come back.
I understand the basic process of marrying, filing for adjustment of status, work authorization and so on. My questions:
1. If we marry, file for status adjustment, work auth, and advance parole, can she go home for a short visit to ease her parents' worries and then come back in a short amount of time? Will she have to get a new visa? What would I have to do to travel with her for that hypothetical short period of time?
2. If we don't marry and she goes home, I apply for K-1 fiance visa, how long can I expect that process to take in terms of actually seeing her again?
I'm obviously ignorant about the process and maybe a little naive but I appreciate all the help I can get.
