Ask HN: Places with a good tech scene and quality of life that aren't in the US?

Some background: I'm from India and I'm doing my undergrad. Until a few months ago, I had aspirations to work in the US. I consider myself quite competent, so I'm not talking about working in sweat shops like Infosys. I wanted to work at Google or Facebook full-time when I graduate (I have done internships with MS and Amazon).

But with Trump's recent spree of executive orders, it looks like my future will be highly uncertain if I go there (assuming of course that people are still allowed to enter the US). I'd much rather work elsewhere where I can have the luxury of not having to worry about my visa everyday.

Before you implore me to work in my own country - please don't. There are reasons why I want to work elsewhere.

So I'm just wondering - what are some other places in the world where there's a lively tech scene (i.e. Big 4 and unicorns have offices), the salary is competitive (maybe not as high as Silicon Valley, but close) and the quality of life is good in general?
