The latest part of Trump's immigrant labor overhaul is to prevent wives of H1-B visa holders from working in the U.S. This undoes a change that went through during the Obama administration, so it will just be going back to before that. Wives of green card holders will still be allowed to work (but green cards are a little bit more difficult to get than work visas). There's not much talk of this in the news, but it doesn't take much to imagine that if there were it would stimulate some debate. It is easy to feel sympathetic towards these wives who won't be allowed to self-actualize their own careers and will have to sit on their hands in the home. But on the on the other hand the country is bringing them in primarily because of the job their spouse is doing. There are a huge number of American engineers complaining they can't get jobs because foreigners have been brought in under the H1-B visa program to do the work for much lower pay. So if foreign workers are going to be brought in for the unique expertise in a certain specialized position, the country hardly needs the spouses of these workers coming in looking for more generalized work, taking those jobs away from other Americans (and in particular American women). All this goes to show how much complication it can create to bring in a foreign worker on an H1-B program, because then it's not only just them but their wives and children who also want to come and look for jobs. (And of course any children who are born in the country are automatic U.S. citizens) If a family from India, or wherever else they came from, doesn't like the terms of their invitation, they don't have to come or stay. Maybe this will start making visa applicants think twice before coming over if they already have a family.
