It certainly doesn't figure into hiring decisions or compensation.
In my experience it takes WAY longer than that, just on processing times. As in, I've never even heard of anyone getting permanent residency that quickly, at least for employment-based. If you are talking about marriage or family-based, sure.
Any audits or RFEs during the process and you are looking easily at twice the time you quoted. Probably even more - given the recent delays in the H4 extension process, which causes your own application to have to wait until your dependents can join you.
If the position is for a company that specializes in French designs, I think it's likely that a French art director might have a better understanding of the domain than an American does.
I like how Hollywood gets a free pass on this. I wonder how it would look with American-only actors.

For the WITCH companies, it's likely undercutting American talent.
Which is why the lawsuit is so ridiculous, why not go after the real perpetrators of H1B problems, consulting companies. Cognizant for example, known abuser of the system to bring in low cost exploitable talent. There's so much shady going on in the system but FB is probably one of the better actors.
