The United States Embassy in Buenos Aires offers an array of information and public services to U.S. citizens abroad including notaries, assistance with overseas voting, income tax information, and Selective Service information.
Most questions regarding these services can be answered via email at BuenosAires-ACS@state.gov . However, if you wish to come to the Embassy, these services are provided by appointment only. If you arrive at the consulate for any non-emergency service without an appointment, you will be asked to return after securing an appointment.
Appointments MUST be scheduled online using the ACS Scheduling System.
