My soon to be ex-husband petitioned me to be an LPR. He filed an affidavit of support together with his mom for me. I am a victim of domestic violence abuse and he kicked me out of our house and he also filed for divorce. I've read that I can sue them for cutting off their support. How do I do that and which court should I file it with?Sorry to add this late... I have been an LPR for 8 years now. I am planning to obtain US citizenship soon. If I file for citizenship, would I still need my soon to be ex-husband?
