If you would like to request an invitation letter from DDW 2018 for your visa application, please use the DDW Invitation Letter Generator. Don't forget to register for the meeting. Once you have registered, you will also have the option to print your invitation letter using the Registration Resource Center (RRC).
DDW encourages you to start your visa application process as soon as possible. Because of new U.S. State Department regulations, U.S. embassies and consulates may require a face-to-face interview for most non-immigrant visa applications. You should apply for your visa at least three to four months before the meeting.
To schedule an interview for the visa application process, please contact the nearest U.S. Embassy or Consulate. For more information, please see the U.S. Department of State website.
