There are a few different attitudes towards dual citizenship. It's not a
simple question, actually, because a few laws make a distinction between
nationals and foreigners. In most cases, it's simple and the person is
treated as a national, having all rights and duties of a "normal" national.
But in some cases, it may not be trivial to decide whether a person is to
be treated as a national or a foreigner if both criteria apply.

Germany doesn't accept dual citizenship, in principle, and revokes the
German citizenship for any citizen who applies for and receives another
one. (And, AFAIK, requires applicants to revoke their previous
citizenship.) But there's a formal process to grant exceptions on request,
and when granted, that other citizenship is officially recognized.

The USA, OTOH, for all I know, doesn't really care whether their citizens
have other citizenships; they simply don't take them into account. A US
citizen is always only a US citizen before the (US) law.
