I was admitted to CLS and it is my dream school; however, I do not have the sufficient funds to study there.
I was considering a loan. Do you think is it worth it?
Is it feasible to pay after graduation? I am very anxious on my decision. I could go to a chepear school, but I Columbia is Columbia!
Hope to hear from you soon!

It really depends on how you evaluate your future earning potential. Without getting into the potential for LLM-emplyability in the US issue (the issue has received a lot of attention on this board), I would say, try to assess how much you may be able to make in your own country (in a worst case scenario) given your past work ex, qualifications, credentials etc.

If you feel reasonably confident after doing the math that you will be ok - just take the plunge! Good luck...
