Hello everyone. My parents are living with me in US. I have filed for their I130 online and received i797 for both of my parents. It has been a month they haven't received biometrics notification. Their visa has expired and i filed petition a month before their visa expiration. Any idea how long does it take to get biometrics notice from USCIS? Also, can i file for their i485 based on pending i130 as well or I should wait till their i130 approves?
Thank You
