Request Invitation Letter

The DDW 2019 Invitation Letter Generator tool is available by following this link. You will also need to register for the meeting when registration opens in January. Once registered, you will also have the option to print your invitation letter using the Registration Resource Center.

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.

Typing

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.
