Do not focus on which has the easiest eligibility as you will need to endorse to where you actually wish to work. And that can take much longer.
NJ requires the CES for initial licensure or endorsement. NY requires the CVS for initial licensure as well as endorsement. And the CES is not accepted for NY, and the CVS is not accepted for NJ.
PA actually requires the CGFNS exam for initial licensure, but it is not required for NJ and NY.
The other thing to pay attention to is that NY does not have any hospitals that are petitioning foreign grads right now, have not come across any over the past two years or so. Even tough if you graduated from nursing school
in NY, so that is something to consider.
