* The following information is provided on an unofficial basis for the sole purpose of assistance. The Protein Society cannot be held responsible for any change in the data. It is the responsibility of the participant to ultimately validate it from official sources, some of which are named below.

Don’t forget to ensure you have a valid passport at all times, and in some cases, a visa. Please check the information provided at the bottom of this webpage on how to obtain an invitation letter from the conference to help you apply and get a visa. American citizens returning home should also be aware that there are new customs requirements in effect. For more information, visit the websites of Citizenship and Immigration Canada and the U.S. Department of State.

Passports and Visas

As of June 1, 2009, everyone re-entering the USA, including American citizens, requires a passport.

The U.S. Passport Card can be used to enter the United States from Canada, Mexico, the Caribbean, and Bermuda at land border crossings or sea ports-of-entry and is more convenient and less expensive than a passport book. The Passport Card cannot be used for international travel by air.

Many other international visitors to Canada do not require a visa, including:

  • Citizens of Andorra, Antigua and Barbuda, Australia, Austria, Bahamas, Barbados, Belgium, Botswana, Brunei, Croatia, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel (National Passport holders only), Italy, Japan, Korea (Republic of), Latvia (Republic of), Liechtenstein, Luxembourg, Malta, Monaco, Namibia, Netherlands, New Zealand, Norway, Papua New Guinea, Poland (with e-passport), Portugal, St. Kitts and Nevis, St. Lucia, St. Vincent, San Marino, Singapore, Slovakia, Solomon Islands, Spain, Swaziland, Sweden, Slovenia, Switzerland, United States, and Western Samoa
