Hi my sister is married to USC. She got 10 years of green card. And she arrived to states about 4 moths now. And she is been mentally and emptionally abused by entire family. She donot know english so she has developed phobia that if she complains it might go against her. And she is been victim of domestic violence, she cannot keep track of everything as she is been monitered for all her actions. And they keep threatening her telling that we will revoke you green card by complaining that you married because of green card and citizenship. But the marriage was done in good faith. Please guide me what can be done appropiate.
