Let’s say I become a citizen of a country that doesn’t allow dual citizenship. During naturalization, new country B tells me I have to renounce citizenship from old country A.
Does that have any effects back in country A? How would country A know? Would country A even care if they found out?
Yeah, being stateless is really bad. There’s a few international agreements to avoid the creation of more stateless people, but it still happens. You end up with people spending years in airports or jails as their visa expires and they have no way to renew it or get a visa for elsewhere, and asylum claims can take months to years to process, and get denied anyway.

Exactly what I was wondering, thanks. I assume you have to renounce before acquiring a new citizenship? No thanks.
No, other way around. Most countries won’t even allow you to renounce if you don’t have another citizenship.
The US also charges $10,000 dollars to accept your renunciation. The US is one of the few countries that taxes its citizens in foreign countries so there’s a big incentive to renounce when you get citizenship in a better place. There is a substantial tax deduction for the first ~150K you earn in another country, as long as you spend less than 10 days in America or traveling and pay taxes in that country, as long as that country has such an agreement with the US.
It’s $2350 to renounce, not $10k.
All the examples listed in Wiki seem very different from what OP is talking about. Most of the stateless persons are located in 4 counties. Crazy.
