Mont. Code Ann. § 37-67-313

A person holding a license or certificate of registration to engage in the practice of land surveying in another state, territory, or possession of the United States, the District of Columbia, or any foreign country may be issued a license in this state if the person applies in the manner required by the board, meets the qualifications provided in 37-67-325, and has passed the principles and practices of surveying examination and the Montana state-specific land surveyor examination. The experience requirements of 37-67-325 may be met with experience gained after initial licensure that indicates to the board that the applicant is competent to practice land surveying. An applicant whose initial licensure in another state does not meet the experience requirements of 37-67-325 must be required to demonstrate 2 years of postlicensure experience for each year of prelicensure deficiency.
