How can I get my NY license if I'm licensed in another state?

Unless you are eligible to apply for an NYS real estate license via reciprocity, you must obtain your NYS license the same way as any non-licensee.
This includes:
1) Complete the 75-hour NYS real estate salespersons course (including the proctored final exam).
2) Pass the NYS state licensing exam.
3) Submit your NYS license application.

The NYS Department of State may waive the 75-hour course requirement if you completed a substantially similar course in your home-state.
