The FNAP Office is responsible for drafting and sending all visa invitation letters: B-1, J-1, and J-1 extension, as requested by a Fermilab point of contact. Non-U.S. citizens can also obtain an invitation letter by submitting an on-site access request in ServiceNow. If there is any change to the activity associated with the visit after the issuance of the letter, please contact the FNAP Office.
For more information on the invitation letters process, refer to the procedure (accessible with a Services account).
