Starting Wednesday, travelers entering the United Kingdom without a visa must apply for an Electronic Travel Authorization (ETA) online.
From April 2, 2025, passports alone will no longer be sufficient for visa-free entry, making ETA approval mandatory.
The ETA serves as a digital security check for travelers and helps strengthen UK border security against potential threats.
Initially costing €10 ($12.80), the application fee is expected to increase to €16 in the coming months.
Although not a visa, the ETA allows multiple entries and stays of up to six months over two years.
Applicants must answer security questions, provide address and workplace details, and upload a passport photo digitally.
The UK Home Office recommends using its mobile app, but applications can also be completed via the official website.
