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.

1. Wanted to check if on an EAD one could work for 2 companies. One sponsoring the GC (Maybe part time) and other full time.

2. Updated FAQ: I have a question in similar line. Currently I am on derivative EAD. My spouse is the main applicant and I got my EAD thru her company. She still works for the same company.
We (me and my friend) have started a company in India some time back. Now, I want to start our new office in the US. Will there be any legal implications? What kind of company I can start here.. LLC or Inc? Please advise.

My self and my wife are on EAD and advance parole. My wife and I are from India.

I have to work in Switzerland on my company business for some time 6 months to a year – would that affect my EAD status in the USA. I would be working for the Swiss branch of my company.The assignment is short term 6-12 months.

This is however not the company with which I started my green card. I changed jobs when I got my EAD.

But I have several questions:
1. Can I even work abroad while on EAD status - short term, i am only talking 6-12 months. if this term is 11 months is that fine? Or do i have to work in the USA only while on EAD?

2. Do I need to maintain substantial presence in the USA while on EAD. And if so what is that term of stay.

3. Updated FAQ: My case is slightly different than the above one. Currently I am on Derivative EAD, which I got through my spouse's company. (I 485 pending and more than 180 days) I was on H1B and I got laid off in March 2009. I am still finding difficult to find a job in the US. I got an offer from a company in Canada. I know that I can work there once I get canadian work permit. My wife (main applicant and EAD holder) will be working for the same company in the US. My question is how often I can come to US with my Advance Parole? will there be any problem if I visit US often? Please advise.
