But in cases where perm was recently approved then with concurrent filing it doesn't make sense to request to file this again.
All in all there are 3 milestone which you have to cross
1. Receipts for 485, EAD, AP filing
2. Bio-Metrics appointment Notice
3. 485 approval notice
In between you may get 485J waiver and/or RFE but these 2 are not mandatory milestone which you have to go thru and hopefully doesn't have to go thru.
