Nurse in Venezuela wants to move to the U.S.A.

Hello, my name is Ivana and I am just starting to study Nursing in Venezuela, however since I have many family members in the U.S.A. (mostly Uncles and Aunts), I would like to move to the U.S. after I have completed my Nursing training here.
Do you know what the requirements are to practice Nursing in the U.S. if one is a Licensed Nurse graduated in another country?

Thank you very much!
Ivana
