Form I-140

Questions,
1. Can I stay in Vancouver while I commute to Seattle for work once a month for a day?
Is there any restriction on the amount of time I need to spend inside the US on H1B?
Is there any restriction to how frequently I can go in/out of the US on H1B?

2. Since my work location would be changing to Seattle from California for me to be able to do this. I am suspecting my PERM will need to be refiled. But given that my H1B is expiring next year and the PERM, I140 process takes almost 1-1.5 years. Can my current company use an older existing approved I-140 petition to help me get my H1B Visa extended? My older I-140 had been approved for more than an year before I left the employer.

3. Will doing this have any impact on my H1B Renewal? I would need to go for re-stamping next year in September.

I applied I-130 for my father to get his GC through Consular processing. I'm a US citizen myself. However I got RFE asking for his birth certificate. I have these queries: The supplemental documents for I-130 for parents as per USCIS application only need US citizen's birth certificate and not the parent's birth certificate. So I don't understand why RFE was issued at this stage? My father was born in the time when the birth certificates were not available. As per the dept of state reciprocity website, it clearly states: "Exceptions: Birth certificates are not available to persons born prior to 1968. " Since it is acknowledged by reciprocity that birth certificates are not available, do I still need to provide NABC (Non-Availability of Birth Certificate)?

I am on H1-B with approved I140. My I94 expired on 10th October and my H1 extension was filed in time. After 7 months of processing time I got RFE even though my employer has filed two service requests requesting to expedite the process. Regardless now that I have got the RFE there is a very high probability that I wont get a response before 240 days which is on 6th June. As far as my understanding goes I am allowed to stay even after 240 days of H1 extension waiting for the decision but not authorized to work. Is that understanding right?

I currently have an approved I-140 with my former employer which is past 180 days. I'm on my H1b (exp May 2021) with my current employer, now my current employer has furloughed me for 90 days and asked to return to work after the furlough period. During this time I'll be paid 20% of my salary or could use my PTO (200 Hours). What options do I have to maintain my status during the furlough period? Can I take paid/unpaid leave and go back towork for the same employer or do I need to find a new job?

1. I work for an MNC, who filed my GC in EB1C, I-140 approved 2 years back, I-485 filed almost 2 years back, completed I-485 interview an year back, also holds a renewed EAD/AP card. My company laid off me recently, so my L1-A will soon get invalid. I got an offer from another company in similar role and responsibilities (SOC code: 113021), so planning to move using AC21 portability. However, my first employer was in e-commerce, whereas new employer in banking domain. So, my new job offer compensation will be 10% less than the salary mentioned in my I-140/I-485 by my current employer.

2. My case is genuine as my current employer is laying off and my role got impacted, with Coronavurus pandemic, it's difficult to find new jobs. Though the roles and responsibilities (role as people manager) will be same, but domain and industry are different and hence, salaries will be different in different industries.

3. Within how months should we file I-485J and what documents do I need to provide to my new employer when joining the company?

4. By the way, my current employer suggested to use AC21 portability to move to any new employer and confirmed that they wont cancel my I-140.

1. I have my I-140 approved 2 months back and my employer is not ready to share the approval notice, is there any way to get it?

2. I am planning to look out for a job change and will my I-140 still be there if I change my employer or is there any time period I have to be with the employer or can they revoke my I-140??, as I am planning to get EAD for my wife on my I-140.
