Yes, I get it. I take that to mean the wifey must go home
No. The way this used to work was that the H1B holder could bring his wife and children on an H4 visa. The H4 visa allowed them to live in the U.S. so long as the husband’s H1B was valid. But they were not allowed to work.
Obama arbitrarily changed this with a “stroke of the pen” move three years ago (a la DACA). Trump is just reverting to the law as it was actually written by Congress.
Granted this sucks if you are that wife on H4. You are no doubt feeling jerked around and unsure exactly how you can comply with ever-changing law.
She doesn’t have to go home, but she can’t stay here.
