Without a robust U.S. training operation, the vast majority of full time imams in American mosques are either trained or born overseas. (The percentage was more than 90 percent in 2013, according to the ISNA study, and Bagby and others estimate that it hasn’t changed much in the past four years.) Most of these visiting imams enter the U.S. with a R1 visa for temporary religious workers; the visas are often good for up to five years, but most imams remain only for a few months. In an effort to stem fraudulent applications for such visas, the number of R1s issued during the Obama era declined significantly from 10,061 in 2008 to 2,771 in 2009. In the following years, though, the number rose steadily and in 2016 the government issued a total of 4,764 R1s.
It is unclear whether or by how much those numbers have dropped during the Trump administration, as statistics for fiscal year 2017 will not be available until next year, says a U.S. State Department spokesman. But judging by the experience of several U.S. mosques this past Ramadan, foreign imams are finding it harder to enter the country in the Trump era.
