Columbia - Harvard --> french student

<p>Hello
Next year, I'm gonna start studying law at Paris 10 (abilingual license). I would like to know how could I apply for Harvard or Columbia ??
What degree do I need to have ??
Can I apply for the summer school in Harvard after one year studying law or is it not enough ??
Can I get in Columbia or Harvard as an exchange student??
What's the cost of living one year in NYC or Boston?? can I get grants??
I need something like the TOEFL, right??</p>

<p>Ok, thats kinda alot of questions but i really need to know. When i called Harvard, they weren't able to tell me about everything</p>

<p>By the way, do you know any columbia or harvard forums??</p>

<p>Thans a lot</p>
