It does get better. The last book was the one I enjoyed most. Without spoiling it, it has some interesting sci-fi aspects that I haven’t really seen/read elsewhere.

The Netflix series covers book one and start of book two (if memory serves). If they do much more, it’ll probably be another few seasons to cover everything… Season two is apparently this year

Just finished the Three Body Problem trilogy. That may be something that fits your ask

Wow, never realised that… Honestly, (rich & power-hungry) humans suck sometimes…

INAL, but if you have eligibility to another country’s citizenship, there is the possibility—maybe even more so in the current US climate—that US citizenship could be revoked. Countries cannot make citizens stateless, so there must a secondary country that you would be eligible to be a citizen of, before the US could make you a non-US citizen.

That said, it seems like anything goes these days, so the big orange fella could change that approach too… Good luck and hope there’s no skeletons to worry about.
