The Drupal Association is happy to issue an official letter of invitation to DrupalCon Pittsburgh attendees who must obtain a visa for travel to the United States. Please note this letter does not constitute any financial commitment on the part of the conference.
If you're visiting from outside the United States, you may need a visa. Please review the United States visa requirements, as you may qualify for a visa exemption.
We urge everyone who requires a visa to apply for it as early as possible. Specific questions regarding visas should be directed to your local United States consulate, embassy or immigration office.
