Extension

My parents are here in US on B1/B2 visitor visa and their I-94 expires on June 5th. With the current Covid Situation, I feel it's risky to send older parents back to India. I would like to know if I can apply for extension of stay based on this situation? USCIS will consider this kind of pandemic situation in to account for extension? If I can apply extension how soon I should do and how long I can extend ( can do 6 months)?

Can H-1B transfer happen in such case from company B? If yes then if this transfer is approved but previous H1b extension is not approved which is from company B will it impact my status in US? Can I work for company B still? Will there be any chance that I have to go to India and come back with stamped visa ?

1. Can I just withdraw the whole petition? and go out of the country and travel back on H4
2. Will withdrawing the "Extension+Amendment" petition without responding to the RFE make my presence UNLawful for the last 11 months. (I-94 Expired Dec 2018 last year) because I worked on the client on their new address without an approved amendment?

My H1B got approved for just 11 months started this October 2019. My H1b is expiring on August 15 2020 and I-94 on August 25 2020. My company will be filing for an extension under premium after February 15th which will be 6 months before my H1B expires. Thinking that I will get my H1B approval notice by end of Feburary 2020 under premium. Can I travel to India during the March 2020 and get my H1B stamping done based on my new approval of H1B given my old H1B is only expiring on August 15 2020. Want to avoid H1B stamping twice if I wanna travel in future after August 25 2020.

Wife's H4 change of status application (I-539) and EAD (I-765) filed concurrently and in process. Can she travel outside country, get H4 visa stamping done and reapply separate EAD (I-765) again?

My father recently renewed his B2 Tourist Visa - and was given the 10-YR Multiple entry visa. He is currently visiting USA and his current I 94 expires in end of May 2019. Due to some medical issues - we were contemplating about requesting a 2 to 3 months extension for his stay - if possible. Would you necessarily have to provide an evidence in the form of a return ticket (about 3 months hence from end of May 2019) - to prove that he indeed intends to go back

Situation:
Resigned company A already and Got offer from employer B and applied H1B transfer(premium processing) but received RFE. But I have another offer from Employer C as well who is yet to file my h1b transfer
Question:<br>
1. If RFE is denied for employer B Can i join employer C with the receipt notice as Employer C has started H1B transfer by that time ?<br>
2. How long one can stay in US without job/payroll having H1B ?

My wife's I-140 was approved and I was also on her I-140. My non-profit employer also filed my PERM and is pending with USICS. If I have to switch employers before my I-140 approval and pending 180 days, I am assuming that my new employer would have to file my GC all over again. Given that I was on my wife's I-140, will I be eligible for H1 extensions after my 6yr period if I don't have my own I-140?
Also, can I change employers and my job roles once I have my I-140 approved and pending for 180 days?
