I wanted to confirm the following if you or anyone else can on this.
The scenario of dependent spouse getting H4 VISA stamped (for the 1st time) and after that H1-B spouse changing the company. If H4 VISA is stamped and H1-B spouse gets new opportunity sooner and transfers H1-B, and both H1-B and H4 are flying from India to US, does H4 spouse need to have new H4 (on H1-B’s current company name) OR H4 VISA stamped on H1-B’s previous company should work at the port of entry?
In this scenario, H4 spouse filed her VISA with all H1-B’s previous company’s documents (and I-797A specially) but principal applicant (H1-B VISA holder) now has a new I-797A. I believe H1-B applicant does not need new stamp (until H1-B existing stamp is valid) but does H4 spouse need new stamp ?
