Oh I see what you mean. Yes, the US thing technically that doesn’t fall under the legal meaning of renunciation. One country’s laws isn’t recognized by another country’s which is why there are loopholes that can be exploited in multiple citizenships, and may also be why people get into trouble if they don’t understand the rights and responsibilities of their citizenship. As someone who once held multiple citizenships, I’ve learned that the only laws that count with respect to citizenship are the laws of the country of citizenship (principle of sovereignty). Whether they enforce it or not is another question, but no laws of another country apply to citizenship of a given country.
