hi! I came to this country on B1 visa. changed it to F1 later on. I got married right before my i-20 got expired. my spouse filed i130. Then he became abusive. I filed a battered spouse case. and now I have i485 pending. I never overstayed and never went out of status. Can I now travel to my country for emergency case with advanced parole before I get approved for GC? What are my chances to reentry the country?
