FBI or CIA? I can speak English and Spanish(near fluent) now, but I would like to learn another, what other languages would be helpful in a career with the military or CIA. I was thinking Arabic. Thanks.
There's also Korean (due to the North Korean threat) and Mandarin and Cantonese (both spoken in The People's Republic of China). Be aware, however, that Arabic and East Asian languages are much more difficult for a native English speaker to learn than is Spanish.
