Hello. And good luck in your ambitions, for me and some friends of mine (nearing college graduation) have been nosing around for careers in the CIA, and while they do like Mandarin speakers, they are extremely suspicious of anyone who has friends in China, as my friend speaks fairly decent Mandarin, but they have grilled him in applications about friends he acquired during semesters abroad in Beijing and Suzhou.
It would all be a matter of whether your language skills outweigh the potential security risk.
