As a dual-citizen, I've had some great experiences at the Swiss Consulate in the US. Though accessing the government through the Department of Foreign Affairs might yield much better service than going directly to the underlying bureaucracy.

Story: when my parents got married, my mother gained Swiss citizenship and they wanted her birth certificate. She told them she didn't have it and that it might not exist anymore, since she was born in South Vietnam, which was no longer a country. They had their colleagues in Vietnam find it for her, and even gave her a copy, without being asked.
