Brits Denied Visa Request for Abdulmutallab

The New York Times reports on a radio interview with U.K. Home Secretary Alan Johnson:

Mr. Johnson said Mr. Abdulmutallab’s application to renew his student visa was rejected in May after officials determined that the academic course he had given as his reason for returning to Britain was bogus. He was then placed on the watch list, Mr. Johnson said, a procedure that would normally involve American authorities being informed of the action Britain had taken.

So, uh, what happened to that U.S. visa?
