Electronic travel authorizations (ETAs) are entry requirements for travelers from visa-exempt countries who wish to visit specific countries. They can be conveniently obtained online for a nominal fee and typically have longer validity periods compared to traditional visas. Here are some examples:
1. eTA (Canada): Costing CAD 7 and approved within minutes, the Canadian eTA is valid for up to five years. It permits stays of up to six months per visit.
2. ETA (Australia): Priced at AUD 20 and approved swiftly, the Australian ETA is issued for one year. It allows multiple entries into Australia during its validity.
3. ESTA (United States): Available for USD 14 and approved quickly, the American ESTA is valid for up to two years. It facilitates multiple entries to the US, with each stay limited to three months.
4. ETIAS (European Union): Starting May 2025, the EU's ETIAS will cost €7 and remain valid for three years. It permits multiple trips of up to three months each within its validity period.
ETAs are distinct from visas in that they primarily track entries and exits rather than grant extensive permissions. Consequently, rejection rates for ETA applications are typically low.
