US employers, please see a recent alert from the American Immigration Lawyers Association (AILA):
AILA has recently received reports that employers have received emails from a contractor at the Department of State (DOS) via clientverification@state.gov requesting confirmation that a beneficiary will be providing services at the company. AILA’s DOS Liaison Committee confirmed with DOS Visa Office that clientverification@state.gov is a legitimate email address. As such, employers should respond to the request accordingly.
