In case you have not read a newspaper lately, M&A work is slow as private equity companies are doing few deals, and fewer and fewer companies are IPO'ing. So, i think that tax law covers both tax and corporate and should help you get in the door whether you do tax or corporate finance.

Noone answered Bob's question about tier 14 schools. I think its important to rank high no matter which school you attend. Attending a tier 1 school but ranking at the bottom will not help you get a job even if you have yoru CPA license.
