EB3 Green Card

How does EB-1C portability work?

I also have a question about the EB1C portability of the priority date. Say, If I have I-140 approved under EB1C and have a particular priority date. For some reason, if I need to or want to change employers and I do not qualify for EB1C with other employers. My new employer can file I-140 under EB-2, or I can file EB-2 NIW myself. I have both options. The question is whether I can use the priority date of the earlier approved I-140 petition under EB1C to the new employer's EB-2 petition and file AOS.
 

Background: Applied I-485 application under EB3 after downgrade from EB2 in 2020. Refiled another I- 485 application under EB2 in 2021. Received EAD/ AP combo card from EB3 application in Jan 2022. Used it to travel out of country in July 2022. Green card approved in EB2 category while out of country. Entered USA using the Advance Parole from EB3 in August 2022 as the green card was in mailbox in USA. At Port of Entry, I informed them about the approval of I-485. However, they paroled me in for 1 year until August 2023 and stamped Advance pare in my passport. I collected my physical card from the mailbox after reaching my home.

Question

What is my status now- Green card or Advance parole?  Any impact on my green card status with that AP stamp as I used AP from EB3 after approval of green card from EB2?  I did not receive any notice form USCIS about withdrawing EB3 application after they granted green card under EB2. Should I ask USCIS to cancel the EB3 application or assume that it is automatically canceled by USCIS?

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 ?
 

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?
 

I am currently working at a company in India. I am eligible to claim Employee Stock Option (ESOPS) on 17th August 2022. However, I will be landing in Dallas, USA on 10th August on F-1 Visa (For Fall 22). The company will still offer those ESOPs, but the official relieving date will be on 17th August. From 9th August onwards till 17th August, I will be on Loss of Pay Leave i.e (unpaid leave). I am worried that situation would create a conflict with my F-1 visa status.

1. I want to know whether this is legal as I will be employed at a company in India for 7 days after arrival in the U.S. on an F-1 visa.
2. Whether this will cause problems in future when I apply for OPT or H-1B or even EB-3 as my previous employment end date is 7 days after arrival in the U.S.?
