► I registered before the Early Bird deadline, but I can't pay before this deadline. Am I still going to get Early Bird registration or do I have to pay the higher fee?

If you have registered before the Early Bird deadline, we will not change the prices even if you are not paid on time. We guarantee that if you made a successful registration at the right time, you will get the price that was on that moment available.


► Can I pay several invoices with one bank transfer?

Yes, you can pay the registration invoice or the registration invoices of you and your colleagues in a single transfer - it is important to write all invoice numbers in the payment description.  


► Can we share bank transfer fees?

The participant needs to pay all bank transfer fees, including the correspondent bank fees.

If you say that bank fees should be divided, a smaller amount will reach the delegate services and you will need to cover the missing amount later.

I need a visa to visit Estonia and join the Conference. How to proceed?

You can request a Letter of Invitation via the registration form.

Letters of Invitation will not be issued to parties who have not registered and paid in full.


All Letters of Invitation will be issued at the discretion of the Conference organisers.

All expenses incurred in relation to the delegate’s attendance at the Conference are the sole responsibility of the delegate and the Conference organisers hold no responsibility for the outcome of an individual’s visa application.
