WHEN SHOULD I FILE MY PARENTS I-485 WAITING ON I-130 APPROVAL?

Question:

My parents are in US for the past 7 months. I’ve filled I-130 for my parents a couple of months back. Not approved yet. When should I file for their I-485?
Thanks

Answer: 

Attorney Mrs. Pallavi Ahluwalia’s response:  The AOS should have been filed before the 90 days ran out. They may be out of status at this time.
