Letter of Invitation
FOR CONFERENCE CHAIRS, TECHNICAL COMMITTEE MEMBERS, AND AUTHORS: Individuals requiring letters of invitation to obtain travel visas must be listed on a paper or in the program to receive an invitation letter. If you are listed in the program, and are in need of an Official Invitation Letter from SPIE for visa application purposes, please fill out and send the Invitation Letter Request Form.
We recommend that you secure your travel visa before registering for the conference as cancellations after the preregistration cutoff may result in a cancellation fee.
