If you are an American Citizen and you are interested in translating for the US Department of State, you can apply as a freelance translator for the State Language Department. Applications are reviewed according to the language needs of the Department of State. If your application is approved you will have the opportunity to go take their language test. I did this last week, partly because I was interested in working for them, and partly because I, as a grader for the ATA English into Swedish certification, was interested in experiencing their testing.
