I got my GC on March of 2016 through my then employer. Soon after getting my GC my project ended (May 2016) abruptly because of the change at client location. I did not had any project at hand so I started looking for a new job and started to work with new employer in June of 2016. There was no official end date of my employment with my previous employer through which I got my GC because they were looking for a new project for me but without any certainty how long it could be before they can find me a new project. While they were looking for a project for me, I already started working for my new employer so I just moved on without any official end date with my previous employer.

In Feb of 2019, I started a second job with another employer. Currently, I'm working 2 jobs full time on GC.

I am now eligible to file for citizenship through 5 years of permanent residency requirement. I'm worried if there will be any issues while I file for my citizenship because I did not stay with the employer that file my GC long enough after receiving my GC. Also will there be any issues because I am currently working 2 full time jobs when I file for citizenship?

Previously I was on H1B when my I-140 was approved. Currently I am on H4 status, not employed and my priority date became current.
Previous employer has provided Supplement J and I have filed I-485, I-765, I-131 concurrently. The Supplement J indicates (#9 in Part 6) I am not currently employed with the sponsoring employer.

Q1) Upon receiving AOS EAD, can I directly join a new employer after 180 days of pending I-485 if sponsoring employer doesn't have any open position?

Q2) Can I start searching for new job before 180 days of pending I-485, but join after 180 days? Or, I must have to start searching and interviewing for new job, only after 180 days?

Q3) At the time of filing AOS, my Supplement J indicated that I am not currently employed with the sponsoring employer. If I join the sponsoring employer upon receiving EAD, then do I have to send USCIS new Supplement J indicating that I am now employed with the sponsoring employer, knowing that it might take a decade for my Final Action Date to become current and I may not be employed with the sponsoring employer at the time of GC interview?

Q4) What if I need to change my employer after GC interview, but before receiving GC?

Q5) I heard, after 180 days of pending I-485, even if I change my job couple of times, I can take the Supplement J only from the employer with whom I will be working at the time of GC interview. But can I still send new Supplement J to USCIS from each employers everytime I change my job? Is that legally allowed? or, is there any concern? Because, it might take a decade for my Final Action Date to become current and within that timeframe I might have to change job 2-3 times.

This is regarding my sister who is going through lot of stress due to visa issues.

She has been on H4 for past 9 years. Her H1 was approved in 2007 with an employer who wanted to hire when she was doing her MBA from a reputed University here in US. They were even willing to hire her once she is done.

3 months back her husband lost his job and had to go on EAD since (My sister could not do it because she was traveling out of US in 2007 when the window opened).

She has decided to go on H1 status. She has to get it stamped outside US as she had lost her H4 status. It has been now more than a month and she is stuck out of US (in UAE). Her employer is a small firm and due to THE bad economy she is very nervous about the future even if she gets H1 B.

Here are our questions/ concerns. Please do answer these:

1. If she gets H1 B could her husband still file for Follow to Join. There is no guarantee in this environment it would give her peace of mind if he could.

2. God forbid - If she doesnot get H1B and her husband files for Follow to Join - would she have to stay out side US to do consulate processing?? How much time it takes?

3. Any advise/ suggestions are welcome.
