My mom had applied for my green card in March 2001 and the date became current in Nov 2008 which is when I received a letter asking me to confirm the address and to pay the fee of 400$. But unfortunately I got married in Dec 2008 thus didn’t pay that amount as I wont be eligible to do so. I am in USA right now on E3 visa and my dad has become a citizen, not my mom. My question to you is can I adjust the status to a green card or will I have to wait for my mom to become a citizen.
As far as I know, there is no way to transfer the priority date over from your mom's to your dad's petition. He can, of course, start another case for you.
