I'm looking to do an online LLM... But I am very interested in attending one which features on-campus residencies. They don't have to be too long or too often (ideally one week per semester or thereabouts,) but I'm having trouble locating anything at all that has residencies. (Besides the Executive LLM in Tax at NYU, but I'm not interested in taxation.)

Maybe if you tell us what you are interested in, there'd be more suggestions.

Only one I can think of off the top of my head is Boston University's Executive LLM in International Business Law, which blends online learning with two-week long residency sessions in Boston.

Why are you specifically interested in an online program? And, why are you looking for residency?
