But I've been waitlisted by Upenn, which crushed my hopes of getting into Harvard :( . I wish to know the minimum requirements that students got in with just to be prepared for the worst. And how much of an influence does my nationality have on my application - in terms of diversity- .
People get into Harvard for different reasons, some students get rejected by many other top schools and still manage to get into Harvard so do not lose hope just yet. Being waitlisted shouldn't crush you because at least you know that you have good credentials.
As for nationality I would say it plays an important role because LLM programs are usually designed for international students and every university tries to get a good number of different nationalities. I believe -but not certain- that they judge your profile against those from your region.
Care to share your credentials? It would probably help previous harvard students answer your question.
