Thanks exbcler - that helps a lot.

Btw, where are you from originally?

Question: Anyone have any idea how likely admission to the BCL program is if you've already received a Columbia JD? I'm thinking about applying to both Oxford and Cambridge after completing my US law degree. Don't care about the practical consequences of this, just more interested in gaining another year of legal training at a new institution....

I believe if you are in the top quarter of your class and if you have strong recommendation letters, you stand a good chance. You may be interested in this:
