Help! I am trying to make an appointment with a counselor in the Social Security department at the USA Embassy in Buenos Aires. I didn't get my payment this month and need to get it sorted out immediately. Dealing with the USA Embassy by phone has been impossible. No one picks up the phone. If I go there in person can I be seen? Someone told me I can't go there without an appointment but wasn't sure. That seems impossible that they wouldn't allow American citizens to come there?
