Immigration information - Invitation Letters

The TTC2023 Meeting will take place at Fermilab (Batavia, IL, United States).

I-94 reminder: If you are traveling on ESTA (Visa Waiver program) or using a B-1/B-2 Visa, Fermilab requires that they enter as a business visitor (WB or B-1), not a tourist (WT or B-2), to come onsite. Please make sure that you get the correct Visa at the U.S. border passport control.

If you require an informal invitation letter for your U.S. Visa application, please contact Evelynn Mendez <[email protected]>.

When you are approved to access the Fermilab site, you will receive an informal invitation (for US citizens) or a formal invitation (for non-US citizens).
