One of the rampage killers in the recent mass-shooting in San Bernardino, California entered on the K-1 visa for fiancés with the intent of marrying her fellow shooter Syed Farook – an American citizen. From 1989 to 2014, the government issued 512,164 K-1 visas. According to David North of the restrictionist Center for Immigration Studies (CIS), this is the first potential terrorist to enter the United States on a K-1 visa.
One potential terrorist out of 512,164 K-1 visas issued is not a good reason to tighten that visa’s already rigorous application process.
