That's sort of what people say about sports law or any other specific area. If you want to go into something like that, I still think your best bet is going to a T25 school. Outside the T25, I do think specializations and clinics and certificate programs and USNWR rankings for specializations matters.
Yeah, I already did that. I'm a lawyer from another common law country and I started a two-year JD with advance standing at a T14 a couple of years ago. Despite my oil and gas background and after doing a pile of on-campus interviews, the only summer job offer I got was to handle FERC work at biglaw in DC. Not that there's anything wrong with that, of course, but it is domestic US midstream regulatory work and not the international upstream work I had been doing before. I wanted to continue along with my international work, so I returned to my home country and have had excellent employment ever since then.
The thing is, I am now in-house at an exploration and production company a long way from home, and I would like to see if I can work my way into a similar role in the United States. (The job I have is rather good, but I miss North America a great deal.) If I got into UT in a two-year program (i.e., with advance standing) and I didn't have to repeat uselessly the first-year curriculum, I'd be there in a second. Now, that is far from guaranteed to happen, so I'd like to know more about the more regional schools that offer a lot of oil and gas coursework. Denver, Tulsa, Houston, and Oklahoma all fit the bill for the purposes of this inquiry. There may be others as well. Perhaps someone here can offer some insight into the smaller schools.
