Applying for ETIAS is a relatively simple process. You will need your personal details, passport details and you will also be required to know your initial point of entry. In addition to that, you will need a visa or mastercard to pay for the visa, and you will need to meet all the requirements listed in the ‘About ETIAS - What are the requirements’ section of this article.
As ETIAS is still in the making, the exact order of the process is yet to be divulged. However, what is know, is that there will be a few short steps and that it will take around 20 minutes to apply.
