Let me just say this regarding international law: we do have a lot of international law offerings and apparently some very strong connections with overseas partners, but unless you actually have the resume for it, it's next to impossible to break into. Some K-JDer with a Political Science degree doesn't just waltz into a job writing constitutions in third-world countries or taking down bad guys at the Hague. You better have significant international resume experience and probably some strong language skills if you want a shot at the prestigious or competitive jobs, and even then it's unlikely to happen. I know people who have done some really cool stuff internationally during their time in law school, but I can't think of any 3Ls off the top of my head who are currently employed in a job overseas. (I'm sure there are a handful, I just can't think of any.)
The people who actually end up working in "international law" generally are people with strong connections or language skills that go off to international branches of law firms. But of course, that's hardly what most people mean by "international law" as 0Ls and 1Ls. They generally mean going off to some country and fighting for the little guy and doing human rights work for an NGO, and there's just not much of that kind of thing out there for a freshly minted J.D. I'm not saying international law doesn't exist like
some people have argued, but it is possibly the most prestigious and most difficult to crack field there is. People just need to be realistic. It always amazes me how many 1Ls come in all bright-eyed about international law, and it shocks me that some are still hooked on that bit by 3L year.
