International Travel to the United States

To Request an Official Letter of Invitation

Once you have completed your conference registration form, please email your full name, address, institution/affiliate name and email address to [email protected]. Once processed, a signed letter will be emailed to you. If you need an original sent to you via post, please indicate so in your email request. 

If you've submitted an abstract or plan to make an oral or poster presentation, you will need to include the title and presentation date/time for your abstract. Presenters are yet to be decided, and will be announced around August. If you'd like to present, please make sure to submit an abstract for our committees to review. 

CERF continues to recognize and support that scientific progress and research is dependent upon the free exchange of ideas among international networks of diverse scientists, professors, researchers, and students.

Changes in U.S. immigration and travel policies have rightfully concerned many international scientists and we respect the concerns of those who may be apprehensive about traveling to the United States due to the travel restrictions.

  • International travelers are strongly encouraged to register for CERF 2019 as soon as possible. This will ensure space, materials, refreshments and other conference amenities are held for you.
  • CERF recognizes that extenuating circumstances, including failure to obtain a U.S. travel visa, may hinder conference attendance. In those situations, with the submission of appropriate documentation, CERF will refund prepaid registration fees.
  • CERF is making efforts to create virtual participation opportunities for CERF members who are unable to travel to the conference. These details are being worked out and will be shared once finalized.
  • Please notify CERF ([email protected]) if you are unable to obtain a visa for travel to the conference, or for other visa-related issues. CERF will track this information to help us understand the impact of visa-related issues on conference attendance. We also encourage you to report issues via this questionnaire.
