- Name (as it appears on your passport) and mailing address
- The name of the conference you wish to attend
- Include your registration confirmation number
- If you are the author of any papers accepted for the conference, please provide the title. If you are a speaker, please provide the title/topic of your speech
- Include a fax number or email address of where we can send the letter
Those requesting a letter should allow up to ten business days to receive it, as requests are handled in the order they are received.
