When a foreign citizen is looking for their embassy, that usually means trouble, but of course there are many harmless functions that go on behind those heavy doors every day. Amsterdam is the capital of the Netherlands, but most government work actually occurs in The Hague (Den Haag), which is about 60 kilometers southwest of Amsterdam.
Italy, Switzerland, United States and the United Kingdom all maintain consulates in Amsterdam, which provide most all services for passport holders of those countries. Dutch Nationals will still have to go to the main embassies in Den Haag for visa information and other emigration-related topics.
The Italian Consulate is just off Rembrandtplein, and the other three are near Museumplein in the south of the city. Check the pages below for more complete information.

Getting to The Hague (Den Haag)
Trains leave from Amsterdam Centraal to Den Haag Centraal about 4 times per hour during the day. The cost is €9.60 each way for an adult. When you arrive at Centraal Station in Den Haag you’ll be a long walk from most of the embassies, but the public transportation there is excellent and identical to the one in Amsterdam. If you have a Strippenkaart in Amsterdam the same one will work for transportation around Den Haag.
