If you (a UW faculty memeber) would like to invite an international visitor to the UW Math Department, follow these steps.

• Extend an invitation to the individual, giving details of the activities, which will take place at UW-Madison.
• Give the specific dates of the person's stay at UW-Madison.
• Give the Amount and type of remuneration, such as reimbursement of travel expenses and an honorarium of $xxxx. Explain that the University may only pay an honorarium for activities that last up to a maxiumum of nine days, and the individual may only accept such payments from up to six institutions during a six month period, and that it is the visitor's responsibility to monitor the number of payments. Reimbursement of expenses only (no honorarium) to a B-1 or WB may be for a longer stay, up to the validity of the I-94.
• Advise them to get either a B-1/B-2 Visa at a U.S. Consulate, or if their country participates in the visa Waiver Pilot Program, they should obtain WB or WT status at the port of entry into the U.S. They can check with the U.S. Consulate in their home country or the INS website to see if they can benefit from the visa waiver.
