Form I-485

My PD - July 2014 EB2. I have a pending 485 and got EAD and AP.
I’m a manager in my current company and manage teams in India and the US.
I would like to know how to upgrade to EB1 as International Manager.
Is it required that I work outside the US for one year?
If I visit India and work for 3-4 months, can the accumulated time over 2-3 years be used for upgrading to EB1?
I would also like to know if we can renew EAD from India and keep the current 485 processes on track.
 

Given the current situation with tech layoffs, I wanted to understand the options available for people in my situation.

I’m currently working in the US on H-1B and my GC application (I-485) with PD July 2014 and 485 is in “Case remains pending”.

I have 485 EAD approved till 2024 and Advanced Parole is still pending.

1. Since we only have 60 days on H-1B to find a new job. How easy is it to switch to EAD? Is there a procedure to follow to switch to EAD?
2. Once someone switches to EAD. Can they again switch back to working on H1 after finding a job?
3. Now if someone switches to EAD and their date becomes current before they can find a job. What are their options?

Now if someone switches to EAD and their date becomes current before they can find a job. What are their options?

Also, do we have any info on what the status “Case Remains Pending” means?

I  had filed for my parent's green card in July' 2022. It is concurrent filing.

The I-130 filed by me shows processing times of 4 weeks and 6 months for my dad & mom respectively.   

The Advance Parole shows processing time of 11.5 months and I-485 (Minneapolis-St. Paul field office) is almost 2 years.

Their I-94 is expiring on the 30th Nov. What is the process to withdraw the application so that they can return back to India legally before 30th Nov?

Also wanted to know:

Will I need to withdraw the I-130 petitions that I had filed for them ?

Will this impact their existing B-2 (visitor) visa? Will it still be valid?

My priority date is April'14 in EB2. My current employer filed an AOS (I-485, I-765 & I-131) using a prior employer I-140 petition. My EAD (I-765)/AP (I-131) was approved a few weeks ago. My current employer didn't submit I-485J while submitting I-485 application. My current employer PERM was submitted a few months ago.

Questions:

1) Is it safe to use the EAD/AP (or) would you recommend staying in H1B until I-485 is approved?

2)  Will this filing be considered to be fraud/misrepresentation (or) Would you recommend withdrawing my I-485 application?

1) How long does one have to wait in total if the company applied for PERM (EB2 - MS CS degree), and THEN Concurrently applied for I-140 (premium) and I-485 and the country of birth is UAE?

2) Can the above be done on an F-1 (OPT + STEM OPT) Visa instead of an H-1B? And any potential issues for F-1 in this case?

3) In this scenario, how would it work if the person also submits NIW in parallel with PERM?
