I don’t know about Sweden, but I think immigration to Europe is easier than immigration to the USA. I recently interviewed with a company in the Netherlands, and immigration was a non-issue. Get job, get residence visa (assuming you aren’t a criminal with a record that shows up in a background check).

Taxes are high in Western Europe, and salary lower than in the USA. That being said, some companies pay wages that are semi-competitive with American wages, and some countries offer a tax advantage for skilled immigrants (in the Netherlands, for qualified immigrants they offer package called the 30% rule, where you don’t pay taxes on 30% of your income & you’re exempt from the wealth tax on assets outside of the Netherlands*)

*don’t quote me on that, do your own research*

Info on the 30% rule in the Netherlands:
