While I agree with your overall point, if you think the US is “easy” to move to, you’re deluded. It’s far easier to move to the UK, Germany, France, Canada, Australia, and many other countries.

As a software engineer that works for a US company, with 15 years of experience, I can work pretty much wherever I want, except America.

The reason your immigration is so lop-sided is because your visa system is a joke. Many of your visas are taken by chop-shops that exploit foreign labour through low wages and threat of deportation. A sane president would make a more granular system that allows easy movement for people from “welcome” countries, while denying visas to specific sectors/countries that manipulate the system.
