Visitors are invited to Stanford from around the world to speak, collaborate and study. Immigration and tax regulations require advance planning 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 made must all be decided before inviting the visitor.
- For information on inviting domestic visitors to Stanford University, refer to Topic Overview: Inviting and Paying Domestic Visitors.
- For honorarium payments, refer to Topic Overview: Paying Honoraria.
- For information when Stanford University students, staff or faculty travel to foreign countries on university business, refer to Policy: International Travel.
Depending upon the type of activity to be performed and type of payment to be made, 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), diplomatic visas (A-1 or A-2) and visas sponsored by another U.S. institution. Stanford must comply with these regulations and visitors are also responsible for complying with the terms of their visa and the associated payment restrictions.
Refer to Resource: Passport and Visa Services.
Fly America Act
If a visitor's travel is being funded by a government grant or contract, air travel must comply with the Fly America Act.
Summarized below are the types of activities visitors are generally invited to perform, the types of payments allowed for each and the type of visa the visitor must obtain to receive a payment.

In most circumstances, Stanford is only able to make payment to a short-term foreign visitor if they enter on a J-1, B-1 or WB (waived business) visa status. Visa application and entry information for each is described below:
A B-1 or WB visa is obtained by the visitor when entering the U.S. on business. Those entering the United States on a WT visa (waiver of tourist visa), may not receive payment from Stanford University. Payment is made to a visitor in the B-1 or WB 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.
The list of participating countries in the VWP (Visa Waiver Program – WB and WT visas) may be found on the U.S. State Department website.
A J-1 visa application is initiated by Stanford by the department inviting the visitor. To learn more about the application process, visit the Bechtel International Center website. The funding for the visitor's visit (Stanford or external) must be indicated on the application.
If the J-1 visa is not sponsored by Stanford, the visitor must receive written permission in advance from their sponsor that they may be paid.

Stanford-sponsored F-1/J-1 (student), J-1 (researcher), H-1B, TN and other non-U.S. citizens authorized for employment in the United States may be paid according to normal university policy as it relates to their status (student or employee) with the university.
In limited circumstances, payment may be requested for visitors on other visa types as described below:

Most payments to foreign visitors are subject to tax withholding and reporting. Withholding and reporting requirements are described below:
Travel Reimbursement (Stanford business purpose)
Travel reimbursement payments to visitors, where Stanford has a business purpose such as inviting an expert speaker to a conference, are not tax reportable.
Honorarium payments are tax reportable. Payments are subject to 30% federal withholding and 7% state withholding (if payment exceeds $1,500). The recipient receives a 1042-S (federal) and a 592-B (state) form at year-end and must have or apply for a Social Security number or ITIN. Foreign visitors from a country with a tax treaty can claim exemption from withholding by filing Form 8233. Refer to How To: Claim Tax Treaty for Honorarium for more information.
If payment is made with the ITIN in a pending status, 30% of the payment will be withheld as U.S. federal income tax until the IRS issues the ITIN to the payee. If the Business Expense team receives the ITIN from the Bechtel International Center before the end of the calendar year during which the payment was originally made, the withheld amount will be refunded to the payee provided the IRS has not informed Stanford that the treaty application is invalid. If the ITIN is not received before the end of the calendar year, the payee must seek a refund of the tax withholding directly from the IRS.
Subsistence and Travel Grants
Subsistence and travel grant payments are tax reportable. Payments are subject to 14% federal withholding. The recipient receives a 1042-S (federal) at year-end. The recipient must have or apply for a Social Security number or ITIN. Foreign visitors from a country with a tax treaty can claim exemption from withholding by filing Form W-8BEN with Payroll. Refer to How to: Claim Tax Treaty for Fellowship Payment for more information.
