Saint Kitts and Nevis sells passports, so I imagine that is the rationale. I see some other microstates on the list that fit that pattern as well.

I suspect that too, and the US is not the only country to be having issues with some of the citizenship by investment countries.

Norway for example, appears to have de-facto banned 5 countries (all on the list) that have such programs: https://www.imidaily.com/europe/confirmed-norway-quietly-den...

Their justification is interesting too, because if the threshold is "citizenship must require personal attendance", then Canadian citizenship is almost certainly invalid too if you obtained yours over Zoom, which is how most new Canadians obtain it.

I'm surprised that you can get non-attendant citizenship in Canada. They don't even give automatic citizenship to children of Canadian parents born outside of Canada (maybe if both parents are Canadian they do, but my experience is with one Canadian and one American). US citizenship for a child born outside of the US to US parents is as simple as bringing their birth certificate to the consulate. And if you marry a Canadian, they won't give you residency unless you physically reside in Canada.

That makes sense, thanks
