NY has the following on their site. At the bottom I also included a link to the site.

If you have been licensed in another jurisdiction and wish to apply for licensure by endorsement, you must provide evidence of:

• Passing a written examination acceptable to the State Board for Public Accountancy; and
• Satisfactory completion of the education and experience requirement in New York State; and
• Good standing as a certified public accountant in each jurisdiction in which you have been licensed.

The State Board for Public Accountancy may accept evidence of five years of acceptable public accounting experience following initial licensure and within the ten years immediately preceding your application for licensure in New York State if, at the time of licensure in the other jurisdiction:

• the licensing standards were not fully equivalent to the current New York State standards or,
• you passed an acceptable examination but under conditions not acceptable to New York State (for example, not passing two or more parts together prior to passing parts singly or not completing the examination within a three year period)

As an applicant licensed in another state you have two options for verification of education, experience, exam and licensing information.

You may:

• have this information collected by CredentialNet. CredentialNet is an independent verification service that will directly verify your education, experience, exam and licensing information. They will then submit a certified copy to New York's Division of Professional Licensing Services for review. You may contact CredentialNet at 615-880-4200 for information on this service.
  
  OR
  
  
• follow the procedures outlined in this application packet for all other applicants. These instructions may be found in the "Completing the Application Forms"
