for Miami, Case, and American I think it depends where you want to practice. Where do you see yourself settling eventually?
All of them are regional. How regional they are for you will largely depend on your class rank. Basically, if your grades and class rank are high, you will have more success in finding a job outside the region/city where the school is located.
Case probably has the best rep in it's market, seeing as they mainly compete with OSU for jobs in Cleveland. Case would probably end up costing you least overall. Even though it is an expensive private school the cost of living in Cleveland will be cheaper than Miami or DC. A good number of Case grads end up staying in Ohio. I would not go to Case if you are uncomfortable with the possibility of having to find work in Ohio or the surrounding states.
American is in DC, one of the most competitive markets for legal jobs in the country. The cost of living will be high in DC as well. American may be a tier 1 school according to USNEWS, but I'd imagine you will face tough competition in DC for jobs from GW, GULC, and all the top schools that send graduates to DC for work.
I think Miami will compete with UF and FSU for jobs, mainly, along with a few high ranked schools in the southeast.
Basically, do not go to any of the schools mentioned above thinking you are virtually guaranteed a high starting salary. Most schools have salary stats that are inflated to some degree, or clearly inflated to the point of being very deceptive.
If anyone tries to sell you on any of the schools listed above based on salary stats or the fact that some of their graduates are working in high paying, prestigous jobs, call the school and ask to see their on campus interview schedule/guide for 2Ls. Now, look closely at the ranking cutoffs some of these employers will request.
Then, look the employer up on Nalp to see how many entry level attorneys they hire and how much they pay. Chances are, the best employers will require graduates of the aforementioned schools to rank fairly high in their class. This means that if you don't have the required rank you don't even get an interview. For schools like these, high paying employers will likely request that students be in the top 20%, top 15%, or even higher. Some employers will only interview students on law review.
If the school is unwilling to disclose OCI information after you've been accepted, when you start asking questions about it, I'd be very hesitant to go to that school.
Good luck with your decision. Maybe you will have luck with some more waitlists.
