I have five friends who've applied to law school after teaching in China, 6 if you count me as one of my friends, which you shouldn't but.. well, anyway.

One went to Yale (but she had a 175 and a 3.98, so..), one went to Columbia, one GW, and one went to GULC. I missed my top choice (UVa) and my other friend whiffed entirely. Looking at everyone's numbers, it seemed we all got in at about the same places we otherwise would have if we had more of a normal post-graduate work experience. So I don't think teaching here would be a big help. But it can be a lot of fun, so, no worries.
