I came here on a J1 with no 2-year requirement in 2011, and I quit my job this year. My DS-2019 stated my program ended August 31, 2012. My I-94 says D/S, which from what I've read, does not mean I'm accruing unlawful presence and is a good thing. However, I am overstaying. I married my wife in August this year, and we are applying for a visa to go back to my home country (pending). However, does this overstaying hurt my chances of getting a green card in the future if we decide we want to live in America permanently? Also, what kind of things would alert USCIS/DHS to my being out of status and get an IJ involved? Thanks for your help.
