Miss. Code § 73-2-11
The board may exempt from examination any applicant who holds a license or certificate to practice landscape architecture issued to him upon examination by a legally constituted board of examiners of any other state or Washington, D.C., or any other territory or possession under the control of the United States, provided that such requirements of the state in which the applicant is registered are equivalent to those of this state.
Each nonresident applicant shall submit, as part of the application, a sworn affidavit stating that neither such applicant nor any person in or agent of the applicant's firm has practiced or is practicing landscape architectural work in this state prior to the applicant having been licensed by the board unless such person or agent holds a license to practice landscape architecture in this state. Failure to submit this affidavit or submitting an affidavit which is false in any respect shall constitute just cause for denial of the application.
An applicant who is a licensed landscape architect but who was admitted in a jurisdiction which did not offer a written examination acceptable to the board or was admitted without the requirement of passing a written examination may be issued a license to practice landscape architecture in this state upon the taking and passing of any examination or procedure as may be adopted by the board, provided that such applicant meets all other requirements for issuance of a license to practice landscape architecture in this state.
The issuance of a license by reciprocity to a military-trained applicant, military spouse or person who establishes residence in this state shall be subject to the provisions of Section 73-50-1 or 73-50-2, as applicable.
