After his first year at Stanford, Romney qualified for 4-D deferment status as “a minister of religion or divinity student.” It was a status he would hold from July 1966 until February 1969, a period he largely spent in France working as a Mormon missionary.

He was granted the deferment even as some young Mormon men elsewhere were denied that same status, which became increasingly controversial in the late 1960s. The Mormon church, a strong supporter of American involvement in Vietnam, ultimately limited the number of church missionaries allowed to defer their military service using the religious exemption.
