Your situation sounds very hard. If your husband is hitting you, you need to contact the police and ask that charges be pressed against him for domestic violence
. You have that right to police protection even though you are on a conditional green card.
Also, you can file for a divorce and seek a division of the marital assets. If he has money that he earns, then you have a right to alimony
and may have a right to some of the property (car and house). The fact that he is physically abusing you will weigh heavily against him in court.
You are saying that you don't have any money. However, if your husband does have money, you can request that the court order him to pay for your attorneys fees in a divorce case.
You should be able to maintain your green card status and residency application even though you are getting a divorce by filing the proper paperwork with immigration. However, this won't be an issue until you are actually granted a divorce by the court.
First things first, you need to call the police and report your husband for hitting you and ask for charges to be pressed.
Then, the question you need to ask your self is whether or not you truly want a divorce. If so, then you need to call around your city/town to divorce lawyers to see if someone will help you. If you cannot find a divorce lawyer to take your case, you can file the divorce on your own. Forms for a do-it-yourself divorce are generally available at the local court house. However, this will cost money. Divorce's have a filing fee of a few hundred dollars, even though you don't have an attorney.
