My parents did 4 months in Conn. when I was 4. Came back with a good accent, and was the coolest boy in the village school, until it wore off 😉 Never been cool since…
I’ve also done a 6 month secondment in Texas when I was young free and single. Had a great time, but I wouldn’t want to live there permanently. Friendship with locals seemed to have so many barriers, that I didn’t really understand while I was there. One US colleague had spent a year or so in the UK on secondment previously, and he really helped make my time there good fun!
I say go for it!
