Overview: Inviting and Paying Foreign Visitors
Visitors are invited to Stanford from around the world to speak, collaborate and study. Immigration and tax regulations require advance planning to comply with these regulations when making payment to a foreign visitor. The type of visa on which the visitor enters, the type of activity to be performed and the type of payment to be requested must all be decided before inviting the visitor.

Compliance Issues
Depending upon the type of activity to be performed and type of payment to be requested, it may be necessary for Stanford to apply for an entry visa (generally a J-1 visa) on the visitor’s behalf. The visa on which the visitor enters the country is one factor that determines the type of payment that can be made. Immigration regulations prohibit or limit payments to visitors entering on most visa types, including tourist (B-2 or WT), business (B-1 or WB) and diplomatic visas (A-1 or A-2). Stanford must comply with these regulations and, additionally, the visitor is also responsible for complying with the terms of his/her visa and the associated payment restrictions.

Summarized below are the types of activities visitors are generally invited to perform and the types of payments allowed for each and the type of visa the visitor must obtain to receive a payment.

Visa Types
In most circumstances, Stanford is only able to make payment to a short-term foreign visitor if he/she enters on a J-1, B-1, or WB (waived business) visa status. Visa application and entry information for each is described below:
B-1 (WB): A B-1or WB visa is obtained by the visitor when entering the U.S. on business. Payment can be made to a visitor in this status only if the following criteria are met:
- Honoraria may be paid if the event lasts no more than 9 days, the service is of direct benefit to Stanford, and the visitor has not accepted more than 5 such payments from other institutions during the previous 6 months. If these criteria are not met, only travel can be reimbursed.
- Subsistence may be paid to collaborators in a lab if the visit does not exceed 6 months. (Note that if the visa is a WB, the stay is limited to 90 days.)
J-1: A J-1 visa application is initiated by Stanford by the department inviting the visitor. To start the application, visit the Guidelines for Requesting a DS-2019 at Bechtel International Center web site. The funding for the visitor’s visit (Stanford or external) must be indicated on the application.
