Most international delegates need either a US B-1 temporary business visitor visa or travel under the Visa Waiver Program (WB status) if their country is a VWP participant. Both cover attending a professional convention such as the NCHCFA Annual Convention & Expo; check your nationality before booking.
Estimated cost: Approx. USD 185 non-refundable MRV application fee for a B-1 business visitor visa; VWP travellers instead pay the ESTA authorisation fee. Confirm current fees on the official US government pages.
Processing: Visa interview appointment wait times vary by US embassy or consulate; check the specific post's wait time on the State Department site rather than assuming a fixed turnaround.
Apply early: B-1 visas require a consular interview, and ESTA under the Visa Waiver Program must be approved before departure. Carry your convention registration confirmation and an NCHCFA invitation letter to support the purpose of your business visit.
