I think that the difficulty immigrating to the United States is a relatively recent development (post-9/11). Lines for green cards have become very long for a lot of people and for some there isn't an option to get a green card (due to non-dual-intent status which is basically "Hey we want you to come spend the best years of your life contributing to the American system and then you have to leave!") One of the bigger problems is that there isn't an entrepreneur visa in the US, which basically means that you can't be on a visa and start a company in the USA. At least in theory. With something like 50% or more of companies being started by people who weren't born in the USA, it seems a bit problematic. It's not impossible to immigrate here, it's just very difficult compared to other developed nations such as Canada, the UK and the EU. I feel like a big problem with tackling immigration in the US is it's so tightly coupled with the partisan issue of illegal immigration from latin america that it's basically impossible to have any sort of reform for legal immigration.
