I (citizen) married an F-1 Student. A couple of months after we married, she left the US for 2-3 weeks for a family matter, and was readmitted on her still valid F-1. (No adjustment of status had been filed yet.) We read later on that this was a bad idea, and that she could've been denied re-entry due to her marriage?!
This was obviously a huge, yet innocent, mistake on our part, and I'm thankful she did not have problems getting back into the US. I'm concerned that her problematic re-entry could come back to haunt us in filing for adjustment of status. Can it? And/or is there anything we can do about it?
