Visa & Travel

Visa Information

If you require a U.S. Visa, we recommend starting the application process three to four months in advance of the meeting. As some consulates may have backlogs in scheduling visa interviews, be sure to consult the U.S. Department of State’s visa appointment and processing wait times webpage. Visit U.S. Visa Information for Foreign Travelers for further information.

To receive a letter of invitation on ECS letterhead via email, request an ECS Letter of Invitation. Upon receipt of your ECS Letter of Invitation, take it to your nearest consulate or embassy to begin the visa application process. The ECS Letter of Invitation does not constitute a visa application. We cannot guarantee that it will enable you to obtain a visa.
