In Poland, you can only vote in your assigned precinct too - there's a list of eligible voters there and you show up with an ID and get ticked off the list - but you can effortlessly change it online, up until a few days before election. The change can be permanent (requires some proof of residence) or temporary, just for this single election (doesn't require anything). You can also get removed from the lists entirely and get a piece of paper that certifies your eligibility to vote instead, with which you can go vote anywhere - this way you don't even need to know where you're going to be on the election day beforehand, but if you lose it, your vote is gone, as it's your token that ensures you can only vote once.

There's also mail voting, but I never even felt the need to figure out how it works. I understand it as an accommodation for people who are disabled or otherwise ill that can't go vote in person. I always lived in cities or suburbs, so voting booth was always within a 10 minute slow walk and I've been always voting in person so far (even when away from home).

Also, in the context of US election, it's probably important to note that voting is always done on Sundays.

We usually get the official results in a day or two.
