US Visa Requirements and Other Information

A foreign citizen planning to enter the United States typically needs to obtain a U.S. visa, which is stamped in the traveller's passport—a document issued by their country of citizenship. Various visa categories cater to different purposes, and for GUADEC24, the relevant category is the B-1 US Visa. This visa is specifically designed for individuals seeking temporary entry to the U.S. for business purposes.
