Please make sure that your center is using nurses that have been licensed in the US, and hold a current license if they are preparing you for working in the US. And have actually worked in the US.
Memberships in any organizations in the US, or even a relationship supposedly with, such as the American Heart Association mean absolutely nothing in terms of preparing you for working over here.
Do not choose a center just on its name, but on the instructor that will be preparing you. Make sure that they are who they say they are, and can deliver what they promise to, or ask for your money back. And get it back.
