Delegates who are not from a visa waiver country will need to apply for a B1 visa to enter the United States. You can read more about the process on the U.S. Department of State website. 

CRYO2019 will provide a letter of support for your visa application. Please note letters of support can only be provided to delegates who have paid the registration fee in full, with the sole exception of Iranian citizens who must register but can make payment at the registration desk.
