If a permanent resident applies for salesperson registration under REBBA, what must they do?

The correct answer is that a permanent resident must disclose their status and provide supporting documents when applying for salesperson registration under REBBA. This requirement ensures that the registration process is transparent and that the applicant meets the necessary criteria established by the regulatory body. Disclosing their permanent residency status helps to verify their eligibility to work in real estate and ensures compliance with the regulations in place.

In the context of the other options, it's clear that they don't align with the requirements as established by REBBA. For instance, there is no specific residency duration, and documentation must be provided to clarify the applicant's status, rather than having no requirement at all. Additionally, sponsorship by a registered salesperson or passing an additional exam is not a standard requirement for permanent residents seeking registration.
