hello, i am a holder of an expired conditional green card. it expired dec 2011. my ex husband and i divorced in 2012 of dec. but we were already separated for a long time. even before my GC expired. i was very naive and financially i couldn't hire lawyer or file for a divorce at that time cuz he constantly cheated on me. in Feb 2013 i married my, now husband, we have one child and another one coming in march. he is also a US veteran. i don't know my current immigration status and would like to start process to be legalized immediately. what should be my next step?
