I am an international graduate student studying in U.S.. I am pretty not sure whether or not it is easy to find job in American university/college (gaining a teaching position) after graduation. I come from China, P.R., and now a physics graduate student in U.S.. I still have many years left to fulfill my degree (now just at the very beginning). My interest is in Exact Solutions of Einstein's Field Equation. I think in future I will pursue some study in Quantum Gravity as a post doctor student. I am not sure whether the job is easy to find in this relevant realm. If it is impossible to stay in U.S., maybe in future I may try to find job in Europe (I can speak very good German). But I am also not very sure whether it is easy to find physics teaching position in a German speaking countries' institute or university. I used to think of Taiwan, but I find that Taiwanese quite dislike Chinese (sinophobia, as you know).
