It wasn’t clear whether the order would hold up in court, but if it did, it would effectively kill the entire H-1B program. That will tend to raise both employment and wages — including for native-born workers in the same industry! So there’s a ton of research showing that the H-1B program is very important and good for Americans. The almost religious zeal with which people attack the H-1B program tells me that there’s something else going on here. On top of that, Trump’s poor treatment of Indian H-1B workers and Korean construction workers will end up weakening America’s alliances — and economic relationships — with those two Asian countries.
