london for career growth - SWE

Good to see an increase in number of Europe-based openings and discussions here on Blind. I’m a student and I finally cracked FAANG internship interview for summer 2021 (FB). The position is in London, and I’m very excited. I want to try hard and deserve that full time offer. I come from a poor country so UK is a major step up. When I was a fresman I was sure I would go (at least try to) go to US. Now I’m not so sure. UK is closer to where I’m from (2h flight, compared to 8h to NY or 15+ to Seattle). Also immigration is easier to deal with in London, and I could get citizenship relatively soon. But what it comes to are the possibilities for career growth. I’d like to gradually take on more responsibility and take the managerial route. I know the best place for this is SV but I don’t want to go there, just isn’t for me. I like Seattle way more and that’s the place I would go in the US. The TC is so much bigger there, but the living costs would be far greater in SV, but in Seattle maybe only a little bit higher than London. Would be able to save the most in Seattle I think. But I also want to enjoy life, so London seems better from that aspect. I know it’s pretty early to think about the future, but I would like to have some guidance on whether to try to relocate or not. London seems like a very interesting city to live in, and is close to mainland Europe which is famous for many cool tourist destinations. It’s growing as a tech hub, and also has firms such as Citadel/JS/HRT that offer good TC in exchange for worse WLB and less interesting, non-product work. So what do you think? Is it a good idea to try to settle in London, or try US out? Also - I’m not interested in people clicking Yes/No, so I’m not attaching a poll. I want arguments.
