This is pretty easy, I did it by myself. If you have issues like DUI in your past, or don't feel comfortable with the paperwork get a lawyer involved.

Hmm, July 2021 is in the future... Please proofread your posts...

It depends how the PERM is written. If it states something like "work from unforeseen locations" it would be ok. If not, a new PERM for the work location would be required. Discuss this with your lawyer.

Yes, it needs to be removed. You file a new application, and provide the GC as evidence of work authorization. You keep the same number.

She would need a Returning Resident SB-1 visa. Otherwise, she won't be able to return. And her visitor visa won't help, because she has shown immigration intent.

You have to wait for approval. Joining with receipt is only possible if the person currently is on H1 for another employer.

For EB3 the employer has to start the process over with PERM. The NIW EB2 is not tied to an employer, and has no Labor certification. It gives you much more freedom. Stick with the NIW.

You would have to extend the GC.

You can of course work from your home country, but you may have to pay taxes there. Both your employer and you should discuss your situation with a good CPA knowledgeable about international tax issues.

An H1 can only be transferred after you have started working for the original employer on the H1. If you don't want to work for the H1 employer tell them now, before they file the H1 petition.

Billable or not is per se irrelevant for an H1. For an H1 it matters that YOU get paid at least the prevailing wage. Where the employer gets the money from to pay you is not really your problem. If the employer is a consulting company USCIS wants to see client letter, etc., of course. For product-based companies they usually want to see product marketing material, etc. It is rather hard to convince USCIS that a consulting company has in-house development. Product development requires a lot of money up-front, which the low margins in the consulting business doesn't provide.

There is no I-140 transfer. The new employer has to start the process from scratch, starting with PERM. The only thing you can take from the old I-140 is the PD.

No. The SB-1 requires that you were unable to travel due to no fault of your own. That basically means if you were in the hospital. Even during the pandemic, most of the time there were flights available.

The condition pretty much rules out any commercial flight. Short of chartering an airplane there are no options. Visit her with the kids in her home country.

You need to start working on the H1 for employer A.
