if one is a master mason, has left one's mother lodge, holds no membership in any other lodge, can they still visit lodges? If they can't, how can they apply for membership in a different lodge?

A Master Mason who has demitted and holds no membership in any lodge is considered unaffiliated, and an unaffiliated Mason has no right to visit lodges 12. The right of visitation is restricted to affiliated Masons who maintain active membership in good standing 12.

To join a new lodge, an unaffiliated Master Mason must submit an application for affiliation 1. Affiliation is available exclusively to those who have attained the degree of Master Mason 1. The application process requires the candidate to undergo a ballot by the members of the lodge 12. Under early Masonic law set forth in the General Regulations of 1721, admission to lodge membership required unanimous consent 2. While this strict standard of unanimity was historically modified in some jurisdictions—such as under the English Constitutions, which permitted admission if no more than three negative ballots were cast—lodges retained the authority to mandate unanimous approval if they so chose 2. Should an application for affiliation be rejected by a lodge, the applicant is permitted to renew the application in another lodge 1.
