This rule prohibits a B nonimmigrant (both B-1 visitors for business and B-2 visitors for pleasure) from "enrolling in a course of study or taking other actions inconsistent with B nonimmigrant status" unless and until the Service has approved the B nonimmigrant's change to "an appropriate student nonimmigrant status." The rule applies only to B nonimmigrants who obtain B status on or after April 12, 2002. It does not apply to B nonimmigrants currently in the United States who were admitted before that date, unless they apply to have their B status extended on or after April 12, 2002.
