Letters of Invitation

Individuals requiring letters of invitation to obtain travel visas to present their papers may access and print an Visa Letter Request Form PDF.

Please fill out a separate form for each person requesting a letter. All letters of invitation will be sent by airmail and by PDF e-mail attachment unless a courier account number or credit card number with expiration date is provided with the original request. Please allow ample time for processing requests. SPIE is not able to contact embassies in support of an individual attempting to gain entry to attend an SPIE meeting. Because the application for a visa can be a lengthy process, we recommend that you start your visa application process as soon as you have been notified that your paper has been accepted. We also recommend that you secure your travel visa before registering for the symposium. Cancellations after the preregistration cutoff can result in a cancellation fee.

For visa application letter and information, please send e-mail to:

Please consult your travel agent or oversea Chinese Consulate web site for visa requirements. If you plan to tour before or after the conference, you may apply for a tourist visa that does not need visa invitation letter.
