Subject to the provisions of this section, the Board may waive any requirement of this subtitle for an applicant who is licensed to practice landscape architecture in another state. The Board may grant a waiver under this section only if the applicant: pays to the Board: the nonrefundable application fee set by the Board; and the license fee set by the Board; and provides adequate evidence that, at the time the applicant was licensed in the other state, the applicant was required to pass an examination and meet qualifications that were substantially equivalent to the examination and qualifications in this State. The Board may grant a waiver under this section only if the state in which the applicant is licensed waives the examination and qualifications of licensees of this State to a similar extent as this State waives the examination and qualification requirements for individuals licensed in that state.
