Attendees from the 27 countries covered by the Visa Waiver Program (VWP) do not need a B-1/B-2 Business Visa to attend NACOB 2008. However, you do need a machine-readable passport.

Participants from all other countries, except the US, will need to go to their US Embassy or Consulate, 120 to 90 days in advance, to apply for a B-1/B-2 Business Visa.  A helpful information page is provided by the U.S. National Academy of Sciences.

Please note that you will need to bring with you to the Embassy/Consulate a Letter of Invitation to NACOB 2008. 

You can download a sample Letter of Invitation here. When you are ready, you can request your personalized Letter of Invitation with your name on it from the organizers of NACOB 2008 by clicking here. Be sure to provide your name, degrees, academic address and email.
