I am a US citizen my husband is Jamaican. We have been married since Feb 2010 we separated 6 months before our 3 year anniversary. He now lives in FL I live in CO we are still legally married but have NOT been living in marital union. He is not on any of my bank accounts anymore I am not on his lease etc.. He still wants to file for citizen ship as he will have been a permanent resident for 3 years in June. I believe he will be in violation and he says we are fine. I have not filed for divorce yet but want to soon. If he files will either of us be violating any laws and if rejected would he be at risk of not being able to file for citizenship after 5 years?
