That's all true, and I had a great time in London and many eu countries.

Do immigrants have the same full rights as British citizens?

Would I be willing to re evaluate my visa every X years? Will I be willing to be uprooted if it's denied?

And how will childcare work when my elders are all here?

I think your post was correct as far as the state of the US, but your final paragraph is reductive. It's not always easy for someone to drop everything and uproot their life, even if it's possible

An immigrant on a student visa was recently elected (or selected by the Green Party because of proportional representation) to be a member of the Scottish parliament. So it’s finally reached the point in the UK where citizenship confers almost no rights that can’t be obtained by anyone coming to the country, even temporarily.
