Change of status

I had an H1B from my previous employer that was valid from Dec 2016-Dec2017. I never got the visa stamped and it has complete 6 years unused on it. The question I need your help with is if an employer files H1B for me, would it be eligible for Cap-Exempt processing or not?

I came to US on H-4, so I have only H-4 stamping in my passport. Got my H1b picked up in lottery two years back, and did COS to h1, and have approved i797A with I-94 and working with my current employer.

Got an offer from another company, and they filed my H1b transfer, and got the i-797A approval with I-94.

So my question here is, can I join the new company using the H1b transfer approval, even though I don’t have H1b stamp at all in my passport? Will this be a valid H1b transfer?, or should I go back to India to get my H1b stamping to join the new employer?

My employer ended my employment due to COVID reasons on May 31, 2020 but I never received an official termination letter. Calculating the grace period depending on the assumed termination date mentioned above, I have till July 30 to find a new job. Should my new employer give me an offer or start the H1B transfer application before July 30? What happens if they fail to do so in time? Can I extend the grace period on the basis of having an offer in hand or maybe because of the pandemic? My final interviews with potential employers are being withdrawn because of the time restriction.

Spoken to the current employer's attorney on Tourist visa , they replied its not a correct path moreover it takes much proofs to tell USCIS i was on H1b working for employer and then changing to visitors and then after certain period of time when i find a project, changing it back (i.e applying) to h1 makes this case more complex.

My wife currently working on H4 EAD which is valid till October 2020. Her company filed for H1B this year and she got approval for 3 years starting 10/01/2019.
However, She would like to stay on H4 EAD. Does law permits her to work on H4EAD even after her H1B approved? or naturally her work visa status will convert to H1B effecting 10/01/2019?

At present I am working in OPT ( expires in June 2020). I have an unused stamped H1B visa which I got in August’ 2013 and my visa stamped in my passport on August,2014. However I never traveled/ worked with this H1B visa and expired in October’2016 without using or entry. I came to USA in January’2016 in F1 Visa. My question is can I use this unused stamped visa for cap exempt as transfer of employer from F1 visa to H1B visa now? or do I need to apply in Master’s cap next year.

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 ?

I am already on a cap-exempt H-1B working for a non-profit full time. Another employer filed my H-1B petition on the cap-subject quota on april 2018 and got an RFE april 2019 and was denied with a reason for maintaining of status. They asked my paystubs from my current employer. My questions are:
1. will there be any impact to my current H-1B?
2. If they only ask for paystubs, can I submit them and initiate motion to reopen the case? what are the possibilities of success.

I was planning on going to India for vacation (after I graduate, before I start work) and I had some questions about whether that would be alright from an immigration stand point. My lawyers are filing my H1B visa application this April; would there be any potential issues with the application if I was to leave the US in May/June?
