Advance Parole

I am a U.S. citizen and I had applied for a green card for my parents and they were in the USA and now they have received their Advance Parole.

1. When our parents have Advance Parole, is there any special process to leave the U.S.?

2. Do we need to inform the airline staff during their check in process?

3. Even though Advance Parole documents specify that parole is valid for one year, is there any advisable timeline they could stay in India on Advance Parole?

4. What is the process for entering the USA on Advance Parole besides showing their parole documents to the CBP (Customs and Border Protection) officer at the airport?

5. Any instructions or guidelines for using Advance Parole?

6. What if their Green card gets approved while they are in India?

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 ?
 

My current stamped visa has expired, I've received EAD & Advance parole (EB3) which is valid till July 2023. I'm still on H1B and haven't used EAD or advance parole. I've a 4 days closed loop cruise trip planned from Florida to the Bahamas. I would be using my advance parole to re-enter the country. If I use advance parole (EB3) to re-enter the country , can I interfile in EB2? Would using advance parole (EB3) to re-enter the country change my status to immigrant and impact my ability to iterfile in EB2?

1) I-485 Filed under EB 3 Downgrade - More than one year back and pending
2)Independent I140 Approved both in EB2 and EB3 (Not as Amendment)
3) Currently working on H1B Work Authorization
4) I-485 EAD and AP Available but never used (EB3 Category)

Questions: -
1) If you change your job but by transferring your H1B (Change of Employer) and NOT use EAD, would the AC21 still apply (Same or Similar Job constraint) if you want to keep the I-485 alive?2) You said the last call that for Same of Similar Determination - USCIS Looks at all aspects:
a) Do the Job Duties and Actual Job Title need to be a dollar-to-dollar match?
b) Job Location Changes (One City/State to Another) and Job Mode Changes (From Onsite to Hybrid or Fully Remote) - Allowed?
c) Compensation Differentials - Positive or Negative - Any specific considerations/grey areas
 

I have a question about Interfiling my GC case. My Priority Date (Aug 2014) is current in the June Visa Bulletin. I'm planning to go to India this month and return back next month. While coming back I will use my AP for POE and also My wife is already using EAD and AP.

1) Can I interfile if I use AP for entering the USA?
2) Can I go back to EB3 if the EB2 date is retrogressive?
