Hi,
I am an immigrant, married my husband abot 18 months ago, he never filled any papers to get me a legal status, because he did not cared, he is an alchoolic, he abused me mentaly, emotionaly and financially, I can not stay with him anymore, is to dangerous for our 6 month old baby.I want to leave him, but I have no idea what can I do...

Contact women shelter in your area, normally they help victims of domestic abuse. Services may vary... better call and ask for help.

It sounds like you will qualify for self-petitioning relief under VAWA. The non-filing of your immigration is typically part of a pattern of abuse and control. You will need affidavits from others that know of the abuse or its affects on you and get an assessment done by a psychiatrist, psychologist, therapist or social worker. If there is a determination of extreme emotional, mental or physical abuse, file the I-360. Your husband will not be contacted by the USCIS. These cases go to the VSC to a specifically trained unit.

there are laws to protect and assist you. consult with an experienced immigration attorney. Good luck.
