I'm curious which way this will go since this is opinion is split in the current administration. If I had to guess, I'm guessing big tech will win, and h-1b will be protected/maximized.
I would argue that SCOTUS tells congress to make a better and more clear law, but Congress never makes one. H4 is not important for big tech as hypothetically speaking partners can stay apart in different countries for the term of the visa. Though imo H4 has more abusers of the program than h1b.
