^ Do you have a source for that? I thought URM has nothing to do with historical inequities, it's called "UNDER-REPRESENTED" minority so wouldn't they be looking for minorities that are under-represented at the school.
Internationals are not considered URMs for the purposes of determining admission to JD programs at law schools that consider URM status. Such consideration applies only to US citizens or permanent residents.
Many law schools do have masters of laws programs which are mainly targeted at internaitonal sudents who have already had law school in foreign countries (in many such countries law is an underegraduate program) and the stats needed to get into one of those masters programs are usually significantly lower than the JD program. Some but not all states allow such students to take the bar exam and practice law in the state.
