I'm seriously considering going back to university within the next year for an international affairs masters. This is one of my special interests, and I certainly wouldn't mind making a career out of it. I've already gotten some interest out of a potential government employer, but frankly, I'm not sure about relying on the government for job offers.

Does anyone have any experience with this?

If you don't subscribe to "Foreign Affairs" magazine, you ought to get a subscription.  It's a quarterly magazine and I think it has some worthwhile articles and will especially be a nice aide in your studies.  I've got to renew my subscription.

What sort of career can you do with that degree?

Government tends to the main employer(foreign service, etc.), but I was thinking that anyone doing business in more than one country (NGOs, big corporations) would be interested. Plus, it doesn't yet have the problem that MBAs and JDs have where the job market is flooded because too many schools offer the degree.

What are JDs?

Juris Doctor, aka law degree in the US.
