So I wouldn't stress the language part too heavily. Unless you're pretty gifted and have more than a couple months to study it'll be hard to reach even moderate proficiency. That's why God invented terps.
Or, if you ARE gifted, go for it. They pay terps (interpreters) some REALLY good money, in the real world. Balog, correct me if I'm wrong, but that's probably not the case there 'in country'. Old guys who had nothing better to do and will do it for smokes or a few dinarii or whatever...?
But, I will tell you that the last 3 jobs I've landed have been EXCLUSIVELY because of my bilingual skills. There are TONS better IT guys than me (I came late to the game, and just sort of 'play one on TV'). How many uber-geeks ALSO can do phone support in a couple of extra languages?
I currently have a standing offer that if I will gain fluency in Japanese, I have a support job guaranteed which will allow me to work from home, but be salaried with full corporate benefits including vacation, holiday, 401k, etc...if it paid more than just a so-so wage, I'd be more pumped-up about it; but I did the Rosetta Stone thing and have gained survival-level Japanese (spoken only-- NOT read/write, which is not necessary to do phone support), and would probably need another 6 months or so to do the phone support.
ANY field you're in can be further enhanced by your knowing additional (in-demand) languages.
Arabic would be good to have, IMO.
