I agree with what "Username" posted. It's a shame you didn't do a BSCS degree [Bachelors in Computer Science] - because then you would have gotten a background in programming and network operation. I would suggest that a good starting point would be a job with GCHQ [Cheltenham] or a similar organisation. Cellphone operation is hot right now, and linguistic skills in Pashtu, Urdu, Arabic, Farsi, etc are quite valuable too. A BSEE would also be useful. Those of us who have that credential become more involved in the hardware/operation end of things than the computer science people do.
My background is in electrical engineering, but i've worked in microwave [those towers you see on mountaintops], satellites, two way radios, the space program, cellphones, and other areas. I changed jobs as opportunities presented themselves - i suspect you will too. I spent a few years overseas at the beginning of my career, and wish at this point i had spent more. The entire Uk is about 10% smaller than Nevada, so restricting yourself to operating in an area that small is very restrictive. As of now, i've worked in 14 countries, nearly all US states, and most of the provinces in Canada. Best of luck!!
