I am facing an unusual situation with my I-485. Priority date is december 2006. Got RFEs for both me and my spouce. Replied to RFEs and within two weeks we got our green cards. Problem is that approval came when priority dates were not current. Any thing unusual in this approval? Spouce's country of birth is Srilanka, but I am the principal I-485 applicat and I am from India. Any one facing a similar situation. Please reply
