Frequently Asked Questions

Submission, registration and payment

If I submit a paper do I have to attend the conference?


You only have to attend if you are the presenting author in an accepted paper.

Therefore, we encourage you to only submit your paper presuming you intend to attend the conference and present it.




Will the conference be physical or virtual?


CEST2021 Organizing Committee is watching closely the on-going development of the global spread of COVID-19, ensuring that all the latest guidelines are strictly followed. We wish to be able to organize a physical event, given the fact that the current situation will improve until September 2021. We have already decided that CEST2021 will be held as a hybrid event, so the opportunity of a virtual presentation will be provided to the participants.




I have submitted a paper, when will I know if it has been accepted?


All the authors will be notified of the final decision by 30 April 2021.




How can I make changes to a paper I have already submitted?


You can send us an email at cest@gnest.org with the exact corrections you wish to make, or the revised manuscript with the changes tracked on it.




Is there a specific template I have to use to submit my paper?


Please visit the relevant section of the website and follow instructions provided to submit your paper https://www.cest2021.gnest.org/guidelines-to-authors .





Papers and presentations

How do I apply for a Visa to come to Greece?


Visa regulations depend on your nationality and country of origin. We suggest that you contact your local Greek Embassy or Consulate for full and official instructions on the specific Visa regulations and application procedures that apply to you.

Where can I get an Invitation Letter so that I can apply for a Visa?


Invitation letters are being sent only to authors whose paper is accepted for oral/poster presentation in CEST2021. Please keep in mind that the invitation letter does not ensure that a VISA for travelling to Greece will be issued.

You can download an invitation letter from Conference Submission platform. After login to your account, you have to click on “My invitation letters” on the left-side menu. Please keep in mind that not all authors are eligible for an invitation letter as being an author of the paper does not make you eligible for receiving an invitation. To make an author eligible for an invitation letter, please assign him as a "Presenting author" or a "Participant" through the edit screen of your paper. If you do not have access to do it, please contact us.
