Pretty much every law school offers LLM programs, and all accept qualified foreign students. The LLM is in no small part a mechanism for foreign lawyers to earn the necessary credential to qualify to take a U.S. bar exam (although it's up to the individual to make sure (a) the LLM is necessary and/or sufficient in the state in which they plan to seek a license and (b) that upon graduation the academic institution they're attending will issue them a degree sufficient to meet that state's requirements).
