For many people, letters of invitation help smooth the visa process and we wish to support international attendees in their efforts to secure the needed travel documentation. However, in order to receive a letter of invitation, the conference organizers must have some assurance that you intend to attend the conference if your travel request is granted. Letters will be issued to those meeting any ONE of the following criteria:

1. You are a current, paid member of ISSX;
2. You are scheduled to present at the meeting;
3. You have completed and paid for your meeting registration fees;
4. You have won a travel award;
5. You can provide evidence of your work or study in the field of xenobiotics

If you require a letter of invitation in order to attend the meeting, please email (indicate "invitation letter" in subject line) the following information to Zoë Fuller at ISSX at zfuller@issx.org:

• An indication of which of the five criteria above you meet, including documentation of your work or study in the field of xenobiotics if you meet only criteria #5;
• The full address that should appear on the letter;
• The name and title of the person to whom the letter should be addressed;
• Whether you prefer that the letter be mailed or faxed (and provide a fax number if the latter is preferred);
• Any other information you believe is needed in order to process your request for a letter or to develop the letter of invitation.

Letters of invitation will be either faxed or mailed via the United States Postal Service using standard international delivery. Due to the costs involved, ISSX cannot send letters of invitation via express mail services. We strongly encourage you to make your request at the earliest date possible. Letters of invitation are sent within five working days of receipt of all requested information.

If you have questions about obtaining a letter of invitation, please direct them to Zoë Fuller at zfuller@issx.org or via telephone at +1 202-367-1160.
