I am currently on an H1B and my fiancee is on an F-1 status. However, we recently came to know that my fiancees father is currently on an un authorized stay in the U.S (Tourist visa) for the last 2 years. I am planning to start the Green Card and Citizen ship process. Will her father un authorized stay in the U.S has any effect when she goes for a change of status (H1B application, H1B stamping) and also with my green card status. Please help!
