Hi, My father has applied for a family based green card for me, he is a permanent resident in the US. I recently received an I 797 "petition approved" notice from USCIS. What does this mean, my priority date is still August 1st 2010. But does this approval notice mean that I am being fast tracked, since I am already in the country on a student visa. Please advise me as to what the next steps on my part are. Thanks.
