How to Request a Letter of Invitation

If you are not from the United States and require a visa to enter the country, you can print a Visa letter during the registration process.

During the registration process, you will be asked if you need a visa letter— please select that this option. Once you have provided complete payment for the conference, USGBC will send you your visa letter.

If you do not get a visa, we will fully refund all conference fees, excluding conference proceedings.

International Delegation Program

The Greenbuild International Delegation Program was established to help international attendees get the most out of their Greenbuild experience. From special registration prices and exposure to the innovative products on display in the exhibit hall to inspirational sessions on advances in the international green building industry, this program is essential for international green building professionals—and those wanting to learn more about the industry.

More details on the Greenbuild 2015 International Delegation Program will be provided shortly.
