EB2 Green Card

Background:

1) PD - Initial Filing - EB2 MAR 2014 (Two Different EB2 filings with two different employers A and B)
3) Downgraded to EB3 with Employer B (New Petition but using the same EB2 PERM with Employer B) In Nov 2020, Filed I-485 Concurrently
3) Change to a different Full-Time AC21 - Same or Similar Role (Employer C) - Using AOS EAD
4) I-485 Got Approved in E26 Category (EB-2) before any I-485J submission whatsoever.
4) Initiated an inquiry with the Congressman to confirm this card is legitimate for usage and no errors / issues; still waiting on USCIS Response.
5) Spouse's I-485 also Got Approved about 2 weeks AFTER this inquiry was already sent over to USCIS (E27 Category).

Questions:

1) Suppose that a congressman's written response from USCIS comes back affirmative for legitimacy of the approvals quoting USCIS discretionary authority. There is also a recent trend of many such approved cases where the applicant had at least one prior approved EB-2 petition with PD current - so this situation does not seem to be unique any more.
Should we still then pursue USCIS E-Request / I-90 submission avenues from our side - would it really be worth to continue stretching this any further at that point ?

2) You had indicated that until notified otherwise, this LPR card can be used for Travel Purposes. Can it also be used to say take up a second week-end / part time job, renewal of driver's licenses etc. ?

3) If you use this card for any of the above purposes, and unfortunately USCIS response were to be negative, do you lose your status - have to do any reinstatement etc. particularly in the travel situation usage of LPR Card ?

4) Can you continue using your AOS EAD / AP instead during this seemingly weird time window, since that also is a USCIS-issued valid non-expired travel and work authorization ? In general, can you continue its usage until the expiry date, regardless of your I-485 status ?
 

Can I change my profession after getting a Green Card? I received my GC in EB2 as an Accountant. Now, I see the salaries in the software/IT sector to be much higher.

1) Is it possible for current PhD students to apply for EB-2 NIW?
I have been through websites where they have said It's Possible, but then why is it not possible for current MS students?
2) Is it possible to work and study in F-1 OPT after completing the degree?
 

1. My previous employer applied for my GC and it just got approved on 07/15/2022.
(a): I have EB3 and EB2 I-140 approved from the same employer.
(b): Filed 485 based on EB3 priority date and received EAD and AP.
(c): No interfiling done to move from EB3 to EB2 and GC got approved.

2. I joined a new employer 5 months ago using H1B with mutual understanding with my previous employer. In case needed, I would join them back. No I-485J transfer has been done so far.

Q: Can I continue to work with my new employer using my GC instead of H-1B?
