Visit the DIS Office

DIS is located in Building 31, Room B2B07, on the main NIH campus in Bethesda, Maryland. Our office hours are Monday through Friday from 8:30 a.m. to 5:00 p.m. We are closed on Federal Holidays.

Campus Access: If you do not have a valid NIH ID Badge, you must enter NIH as a visitor through the Gateway Center. Check out the NIH Visitor Information webpage for more details.

Ask DIS a Question

DIS provides services that make it easy to get the immigration information you need. If you cannot find the answers you are looking for on our website, here are other ways to contact us.

Email: Send your question to the DIS Customer Service Team at: Our goal is to respond to emails within two business days, but no later than five business days.

Phone: For urgent questions, call our office at (301) 496-6166. If our phone officer is unavailable, we will return your call within one business day.

Walk-in Advising Hours: From 1:30 p.m. to 3:30 p.m., Monday through Thursday, an Immigration Specialist is on duty to talk to NIH foreign nationals, administrative staff, and sponsors. This is an easy way to ask quick questions! For example: travel signatures for NIH-sponsored J-1s, travel-related questions, general immigration, or case preparation questions.

Appointments: Call our office at least two business days ahead of time to schedule an appointment. This is the best way to discuss complicated or case-specific questions. Questions that need more than 15 minutes with an Immigration Specialist would ideally be handled with an appointment.
