International Visitors
What Do I Need?
For Visitors in Need of a VISA
If you need a visa, you will need to apply for the right kind of visitor visa. It is normally a B1* visa: Attend a scientific, educational, professional, or business convention or conference for a business visit.
*Please check current visa categories and requirements with the U.S. State Department.
Visa visitors must have a machine-readable passport and schedule an in-person interview with the U.S. State Department consulate or embassy. The application process varies by location. Please contact your local consulate for the most accurate information.
It can take up to four months to get an interview date. Please contact your nearest consulate to request an interview date and file your visa paperwork as far in advance as possible.
If your visa application is denied, please inform the conference organizers (i3ce2024@andrew.cmu.edu) by July 1, 2024. Please attach a copy of your visa denial.
Please note: ASCE will not intervene on behalf of the invitees with the Embassy or U.S. Consulate via fax, phone, surface mail, or email. The U.S. State Department provides information on traveling to the United States regarding passports, international travel, and visas.

Visa Waiver Program and ESTA
Travelers from VWP countries must have valid Electronic System for Travel Authorization (ESTA) approval before travel. U.S. Customs and Border Protection will handle emergencies on a case-by-case basis.
ESTA requires all international travelers from VWP countries to register in an online database. Travelers from VWP countries must complete an application on the ESTA website.
Travelers are not required to complete an I-94W form before each trip. The ESTA requirement does not affect U.S. citizens returning from overseas, people from VWP countries traveling on a valid U.S. Visa, or travelers from non-VWP nations.
Visiting International Fellow (VIF) Applications
Annually, EWRI invites applications for Visiting International Fellows (VIFs). The fellowships provide support for faculty, professionals, or student researchers from developing countries to participate in the annual World Water & Environmental Resources Congress, and in supplementary activities during their visit to the United States.
The fellowships increase participation of water resources and environmental professionals from developing countries in EWRI conferences, and promote sustained professional and cultural exchange.
