Have been a silent reader on this forum and I would like to say a big thank you to Q, Spec, Idliman and other gurus who have been helping so many of us.
I have a unique situation and not sure what to do next.
I was employed by Company A since 2011, filed 485 on 10/21/2020 in EB2 with PD June, 2010. Submitted medicals, I944 and 485J along with my 485 application. On 11/3/2020, our company announced that it will be acquired by company B from 1/1/2021. Company B updated the public access record and established successor in interest for H1-B through a notary paperwork, they did not do H1-B amendment nor transferred my H1-B. I am on company B?s paystubs from Jan 1st 2021.
For GC, company B?s lawyer said we can file 485J after completing 180 days as Company A?s federal tax ID is still active. Tried to convince her to file I-140 to establish successor in interest but could not succeed. Gave my fingerprints on 3/22/21.
Fast forward, I completed 180 days on 4/19/2021 and company B prepared new 485J and mailed it on 4/30/2021. I was hoping that it might trigger something as my pd was current in May. Irony is I got receipt for old 485J on 5/1/2021.
My 485 application got approved on 5/11 and today I see that old 485J got approved as well. Reached out to the lawyer and she mentioned that worst case, my 485 case could be reopened to process the new 485J. Since we have proof that a new 485J was submitted prior to the approval in case any question may arise.
Approval has not sunk it yet as it all happened in such small span of time.
Don?t want to sound negative but being in backlog for the last 11 years makes me think of all possible scenarios.
1) Dependent?s H1-B is up for renewal in Sept, 2021. If we do not proceed with his H1-B renewal and 485 case is reopened, can he continue to work given our EAD and AP cases are in pending status?
2) Can this have any impact down the line when I apply for Citizenship?

Thanks in advance!
