You must obtain access approval before arriving onsite.
The access approval process could take anywhere from a few days and up to four weeks depending on the specific situation, so we encourage you to register early.
Once you register for USMCC, an access request will be automatically created for you. You will receive an email from Fermilab Service Desk <fermi@servicenowservices.com> containing your access request number.
Upon approval, you will receive an informal invitation (for US citizens) or a formal invitation (for non-US citizens) with a QR code.
You can check your site access status using your access request number: ServiceNow (servicenowservices.com)
