Please come to building 35 and call us. You'll need to go through security at the NIH Visitor Center (right near the Metro). You will need an ID (see below.) It's about a 15 minute walk from the visitor center to get to us.
Security timing: It often can take 15 minutes or so to get through security on foot or via Metro. If driving or in a taxi, you can go through the vehicle inspection and wait, but they suggest giving an hour for that process. It is often faster than that.
Forms of ID:
US citizens and permanent residents: We apologize for the hassle but a driver's license is only valid if it is DHS compliant. As of May 2016, Illinois, for example, is not.
International travelers: Please bring your passport and a record showing you were invited to visit.
