Participants should check if they require a visa to enter the United States on the U.S. Department of States U.S. Visas website https://travel.state.gov/content/travel/en/us-visas.html
Foreign travelers, who are citizens from certain eligible countries, may also be able to visit the U.S. for business (e.g. attend a scientific conference) or tourism for 90 days or less without a visa if they meet the Visa Waiver Program requirements (https://travel.state.gov/content/travel/en/us-visas/tourism-visit/visa-waiver-program.html). All eligible travelers who wish to travel under the Visa Waiver Program must apply for authorization on-line through ESTA (Electronic System for Travel Authorization) at https://esta.cbp.dhs.gov/esta/.
If you require a visa to enter the U.S., we strongly recommend that you start the visa application process as soon as possible.
Non-US participants will need to present their passports with vaild visa to enter BNL.
