Marry to the green card holder

When you say that the girl does not have any documents, I assume that you mean that she did not enter the country legally. If so, she will have to leave the U. S. in order to get the green card unless she is a beneficiary of section 245(i) under which an individual can adjust status to permanent residence in the U. S. if he or she had a labor certification application or visa petition filed by April 30, 2001, and was physically present in the U. S. on December 21, 2000. It would likely be faster for her immigration if you became a U. S. citizen. I note that if your girlfriend has been here without status for 180 days or one year after entry without documents, she would be barred from entering for 3 or 10 years respectively if she left the U. S. You and she may explore the possibilities of her applying for an I-601A waiver based on extreme hardship to you when you are married. Unlike the regular I-601 waiver which is only available after denial at a consular interview, the I-601A allows a qualified individual to submit a waiver application of the 3 and 10 year bars while in the States and wait for the result before deciding to go overseas for consular processing of an immigrant visa.
