I had top 10 to 20% grades from a top six law school and I'm a 5th year at a BigLaw firm's foreign office in Asia considering a switch into tax.

I'm considering getting an LLM in tax. I'd like to practice in BigLaw or Big 4 in the US after getting the LLM (at NYU, Georgetown or Florida).

Does anyone know if the fact that I've had the credentials for and been in a BigLaw firm hurt or help my future employment prospects relative to other students in the program?
