The International Civil Aviation Organization (ICAO) has welcomed the European Commission's plans to adopt a proposal that will establish a European Travel Information and Authorisation System (ETIAS) to strengthen security checks on visa-free travellers.In notes on an ICAO symposium, the body explained that similar to existing systems in Australia, Canada and the U.S., the purpose of ETIAS is to assess in advance of their actual arrival at the border the eligibility of visa-exempt travellers to cross our external borders and, in particular, whether their presence would represent a security threat."ETIAS will introduce an additional layer of systematic control compared to the current situation (without ETIAS) by allowing for early checks against relevant databases and assessment of the security, irregular migration and public health risk," wrote ICAO."While these checks are already routinely conducted in the visa-issuance process, no information was recorded on visa-exempt travellers. ETIAS is intended to close the "information gap" on these travellers."
