The B-1 Visitor Visa is intended for business and professional purposes such as:
WB Business and WT Tourist Visa Waivers are available to citizens of some countries who may enter the U.S. for 90 days without needing a visa. See a list of countries who participate in the Visa Waiver Program.
There are restrictions on the kinds of payments that tourists may receive in the U.S. Likewise, international guests and visitors who receive honorariums or payments associated to incidental expenses and/or travel expenses are subject to taxes imposed by the Internal Revenue Service. The hosting school or department is responsible for reporting to the Comptroller's Office when any Illinois State funding pays for tourists' airfare, lodging, honorariums or gifts.
Departments may contact the International Tax Specialist at firstname.lastname@example.org or (309) 438-7677 for assistance and advice on what kinds of payments or support are appropriate for a visitor's visa type and the best interests of the University and visitor.
