I got married in November 2004 to U.S. citizen. In august 2007 I got Green Card for 10 years. We divorsed in December 2007. Married in good faith and in January 2006 our daughter was born. Recently, 31 of March 2010 I got letter from immigration which says, that we divorced Dec.11.2007 and it also says that on Dec.13.2007 form I-751 was aprooved by error. It been 2 years since we got divorced, and so suddenly they want to take my permanent resident status from me. I am single mother and I can't afford lawyer. I did all my paperwork in Virginia and now I live in PA. I have no criminal. Please, help me is this is something I have to worry about or not? Thank you
