I find it hard to believe anyone would voluntarily move to the US(¹) as a foreigner given the current political climate and attitude of the regime towards immigrants. Solidarity with those that the current policies are directed against, should be reason enough not to move there.
the above sounds a bit condescending which wasn't my intention at all, there are many private reasons why somebody would still want to move there. If your only motivation is to move overseas and work in a cutting edge project there are plenty of cool companies in Berlin, Zurich (Zug), Singapore, Tokyo, ...
You can make a really good salary in Europe as a freelancer provided you got enough specialization and skills. (hourly rate in Germany, France, Switzerland are starting at €70-€90 and up for software engineers).
Thx! I totally understand what you mean. But still if you want to work on cool products that are used and loved by a lot of people, the silicon valley is one of the best places to be.
¹ same holds true for the UK.
