The R-1 Visa enables religious workers (those working in a religious vocation or occupation) to temporarily enter the United States. A religious vocation is defined as a calling to religious life, shown by a demonstration of a lifelong commitment; for instance, taking vows. Nuns, monks, and religious brothers and sisters are examples of religious workers. A religious occupation is defined as a continual engagement in an activity related to a traditional religious function. This definition includes liturgical workers, religious instructors or cantors, catechists, workers in religious hospitals, missionaries, religious translators and religious broadcasters. However, it doesn’t include janitors, maintenance workers, clerks, fund raisers or solicitors of donations. Your spouse and/or unmarried children under 21 years of age may be granted derivative status to enter the US. They are not authorized to work while in the US, but may attend school.
