B-1/WB Statement describes who can come to NIH in B-1 or WB status. If your IC would like to invite a foreign national scientist to the NIH for a stay of less than 90 days in B-1 or WB status, you are encouraged to route the case through an approved B-1/WB Delegate at your IC. DIS has a
list of current Delegates on its website. The B-1/WB Delegate will issue the appropriate B-1 or WB invitation letter.
Remember that all WB visitors need to register for ESTA and all Chinese visitors need to enroll in EVUS before departure from their home country. All visitors who register for ESTA must apply at least 72 hours before their international flight is scheduled to depart. If the IC requests a badge for the visiting scientist, the Delegate must send DIS a “Notification of Arrival” packet with relevant documents upon the scientist’s arrival to the NIH.
All foreign national scientists who are coming to the NIH for a stay of more than 90 days in B-1 or WB status need final DIS approval before coming to the United States. The IC should send DIS a
case for these scientists.
