"Finally, some people who become US citizens hope to take advantage of the fact that the US didn't make them actually go to their old country's consulate and get their citizenship revoked (all they were required to do was make a renunciatory statement as part of the US naturalization oath) -- and so they continue to exercise rights of citizenship in the old country as though nothing had happened. The US State Department used to take a dim view of such behavior if they found out about it, and people acting in this way were known to lose their US citizenship on the grounds that their pledge to renounce their prior status had evidently not been made in good faith. Now, though, the State Department almost never pursues such cases."
