I485 Adjustment of Status - AC21 Portability

[SRAVKY]

I am working for Company A on H1B and they have processed my green card based on approved Company B I140. Priority dates got ported.

 

Company A - EB3 Jan 2009

Company B - EB2 Jan 2009

 

With new AOS chart, I am eligible for applying I485 through Company B. Company B still has open job offer and are willing to support the Adjustment of status process. I am planning to go ahead with the process but have couple of questions -

 

Questions:

 

1. Can I file AC21 through Company C (again future employment) and move out of Company B after 180 days of pending I485 application? Since my GC is for future employment, I have never worked for Company B.

2. If above is possible then if there are any RFE's, will the new company (Company C) be answering them?

3. Can I continue working for Company A on H1b until I get green card and then start working for new company.

4. Once I get green card, should I be working for Company B or C?

5. What are the criteria for filing AC21? Should I be having the labor information with me?

 

Please help me out with above questions.
