International Attendees

The Air Quality Conference appreciates the input and diversity that international attendees provide. We welcome your participation and encourage you to register early to accommodate the necessary paperwork required.

U.S. Visas
U.S. visas are issued by American consular officials according to the requirements of the Immigration and Nationality Act. Federal regulations now require more thorough visa processing, so international attendees are encouraged to apply for visas 3 to 4 months in advance of the conference. International attendees are solely responsible for all forms, filings and contacts with a United States consulate in their country of origin to obtain a visa to enter the United States. The EERC cannot intervene on behalf of the invitees with the Embassy or Consulate via fax, phone, surface mail, or e-mail.

Letter of Invitation to the International Conference on Air Quality
Attendees requiring a Letter of Invitation for the passport and visa application process are required to first register and submit payment for the conference (visit our online participant registration). Then submit an e-mail to LaRae Foerster at lfoerster@undeerc.org requesting the letter. Once you have submitted your registration, and we have received your payment, an invitation letter with original signature will be sent by mail via the U.S. Postal Service using standard international delivery. Due to the costs involved, the EERC cannot send letters of invitation via express mail services or fax. For security purposes, we do not e-mail letters.
