Conference participants should familiarize themselves with visa requirements well in advance of the conferences. The 2023 Cryogenic Engineering Conference & International Cryogenic Materials Conference (CEC-ICMC 2023) Organizers encourage you to apply for your visa as early as possible, at least 3 to 4 months prior to this conference.
Please note: Some consulates may have backlogs in scheduling visa interviews. Visa Wait Times for Interview Appointments and Processing by City are available here.
CEC-ICMC 2023 CANNOT INTERVENE with U.S. Embassies abroad or the State Department on behalf of any participant. However, if you need a personal letter of invitation to attend the Conference, please contact Centennial Conferences (email: email@example.com or fax:  303-499-2599) and provide the following information:
- Full Name
- Complete Mailing Address
- Fax Number (if you wish to receive a faxed copy of the letter)
- Abstract Control ID(s)
The letter we provide you will reflect your status as known to us at the time (abstract accepted and a place in the program assigned; paid registration received, etc.). The letter does not imply financial support from the conference. Your letter will be EMAILED to you. A hard copy will be faxed and mailed to you via regular airmail only if requested. Any fees for sending letters via express mail must be paid for by the requester.
Please note that letters of invitation can only be sent to presenting authors of accepted abstracts or registered and paid attendees and exhibitors.
The majority of oversees attendees will be eligible for the “Visa Waiver Program”. Details can be found here.
If any problems are encountered in the visa applications or in the admission process, please submit your report to the International Visitors Office by completing the questionnaire on their website. To help the International Visitors Office to identify you as a participant, please be sure to include the 2023 Cryogenic Engineering Conference & International Cryogenic Materials Conference in the “Purpose of Visit” field on the questionnaire. The International Visitors Office can inquire at the Department of State about the status of visa applications that have been pending for more than 21 days.
