I'd like to congratulate you on getting into Boalt! I graduated from Berkeley last May, and absolutely loved it there! I'm sure you'll love it too. =) Let me know if you have any questions about Berkeley, food, fun things to do, etc.
I am also thinking about writing somewhere on the lines of immigration and ethnic identity. If it's not too weird or inconvenient (since we don't know each other), could I also take a look at your ps? I've read all the ones in the Montauk book, but would like to read a more recent ps. Plus, it seems that your topic is similar to what I'm thinking about. Thanks!
