AC21 AOS Portability

I have applied for EB3 downgrade last October, received the EAD cards, I-140 is still pending. What would be the process for me to change employers at this time? Does the new employer need to start the GC process all over again? As the 180 days have passed since the I-485, what would be the process to use AC21 when I-140 is still pending for same or similar occupation?

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?

I have a situation of my relative - person has the employment based green card received on Mar 12, 2012, Received EAD in 2007. However lost the job(job termination) (Nov 2, 2011) 4 months before to receive the Green Card. At the time when GC was approved (March 12,2012) person was not having the job, and there after person couldn't gone to job. Could you let us know what to do for GC renewal and for citizenship.

1. Is submitting consolidated returns and audited financial statements for a parent company and its wholly owned subsidiaries sufficient to meet the burden of proof for establishing the company’s ability to pay by a preponderance of the evidence?

2. Where an employee who is the beneficiary of an approved I-140 and is eligible for AC-21 portability ports to a new employer in the same or similar occupation, must the new employer demonstrate the ability to pay the proffered wage from the date of portability?

3. When adjudicating I-485 applications for portability-eligible individuals where the petitioning employer is no longer in business, does USCIS require the subsequent employer to satisfy both the ability-to-pay requirement and the bona fide offer of employment requirement from the date of the employee’s subsequent hire through the approval of adjustment of status?

4. Why are prorated net assets not sufficient evidence to support ability to pay?

5. Why is the Yates Memo not applied if a beneficiary’s W-2 indicates that the actual wage paid to him/her is at least as much as the beneficiary’s proffered wage for the prorated period?
