As a prominent figure in the occasional capital of a distant province of an occasionally unstable nation, Larkin stood in a position of influence that could easily have been his undoing if he chose the wrong side. The fact that he was able to survive through shifting administrations is testimony to his political skills. Despite being a supporter of Governor Juan Bautista Alvarado, he did not involve himself with Alvarado's accusations against Isaac Graham and other foreign residents of the Monterey area, and was not one of those sent to prison in chains in 1840. Larkin loaned money to Alvarado’s successor, Micheltorena, which he lost when the Governor was overthrown by Alvarado in 1844. He never applied for Mexican citizenship, which required conversion to Catholicism; instead he renewed his visa annually to maintain his legal status. As a non-citizen, he could not legally own land, but he managed to obtain land grants in the names of his children.
