Intel was the top H1B sponsor a few years back. Presumably they hollowed out their talent base by hiring less experienced engineers for less pay. Some of whom have returned home or are now working for a competitor closer to home.
I’ve got many friends that joined Intel on an H1B and are now holders of/in the process of getting green cards. The company starts the sponsorship process very quickly and most h1bs in chip design/manufacture probably tend to continue in the US.
