Dear Professor _____________
We are so pleased that you will be visiting Stanford to speak at our _______ Research Workshop on [date]. To show our appreciation for your willingness to share your research, we would like to offer you a modest $_______ honoraria, assuming your visa and tax status allow you to accept this. Please be aware that honoraria payments may be subject to up to 37% withholding. In order to process this, we will need you to complete some paperwork; we will be in touch shortly about this. If you would like our assistance securing a visa to enter the United States, or an ITIN (tax identification number required to receive honoraria payments), please let us knowwe will be glad to help with this. We are also prepared to cover the costs (up to $______) for your travel to and accommodations in the Stanford area. We can make and pay directly for travel arrangements for you, or, if you prefer, we can reimburse your for reasonable expenses (i.e. coach-class airfare for flights under eight hours in length, no entertainment or alcohol-related expenditures, tips 15% or less). If you choose the latter option, we will provide you with the forms and information necessary to be reimbursed by Stanford.
Sponsored by a grant form the Mellon Foundation, the Research Workshops at Stanford are unique spaces where scholars from a variety of disciplines and professional cohorts meet to discuss work in progress in their fields of interest. I think you will enjoy a lively exchange of ideas with a diverse audience of faculty and graduate students in your workshop. We will most certainly enjoy the opportunity to meet and exchange ideas with you in this informal, collegial atmosphere.
