Certain persons working in a religious field can also apply for a GreenCard. However, unlike in the similarly defined non immigration visa R-1, it has to be proven here that the applicant has already executed some kind of religious work for a church or community in his home country for at least two years. Membership alone is not sufficient. An examination of the job market is not necessary, however, so that this still proves a quite easy possibility for obtaining a GreenCard.
