How can I get my CA license if I'm licensed in another State?

California does not offer reciprocity with any other state.
For this reason, you will have to go through the same licensing process as any other non-licensee.
First, you will have to complete the required 3, 45-hour pre-licensing courses. Next, you will have to get fingerprinted and apply for the State licensing exam. Once you pass the state licensing exam, you then apply for your California real estate license.
