how to apply for Licensure?

Moved to the International forum as per the red banner

You are not applying for NCLEX but licensure to be a RN in the US of which NCLEX is a part of that process. Title of thread changed to reflect this

We do not recommend Ca for initial licensure as they will not give you a license without a SSN and after 3 years your file will be deleted and with retrogression you are looking at currently of a longer time frame. Suggest you read the sticky titles Prier to working in the USA and threads on California and retrogression

See: California: Nursing Schools, Board of Nursing, NCLEX pass rates, etc.
