Why would you travel to a country other than your own country? People usually migrate to some other country for education, job, business, medical treatment, meet their family and friends, or tourism. There may be any purpose, but it is not possible to land into any country without an immigration document in your favor by that country’s Embassy or High Commission in your country, usually called consular office for immigration purpose.
Better solution to visa
There are few countries in the world that attract many visitors/immigrants every year that visit to these countries for any of the purposes specified in the previous paragraph, but most common are tourists and business visitors. The consular offices of these countries usually have heavy load of visa processing. The countries such as United States, Canada, United Kingdom, and Australia attract most immigrant every year, but United States and Australia have found ample solution to deal with the workload of visa processing.
Advantages of ETA in lieu of Australia visa
Both United States and Australia participate in Visa Waiver Program (VWP) that helps in reducing visa issuing burden. For instance, Australia ETA is an Electronic Travel Authorization which is issued in lieu of visa to tourist/business travelers of specific countries who intend to visit Australia for short duration not exceeding 90 days. Thus, both Australian consular offices and travelers save lot of time, money and efforts on visa processing. Australian consular office’s lot of administrative work is reduced in this way and a traveler also gets ETA electronically without visiting Australian consular office.
Who can get ETA for Australia?
The important thing to remember is that Australia ETA is not for all countries because passport holders of Andorra, Austria, Belgium, Brunei, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong (SAR), Iceland, Ireland, Italy, Japan, Liechtenstein, Luxembourg, Malaysia, Malta, Monaco, The Netherlands, Norway, Portugal, Republic of San Marino, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, UK, USA, and Vatican City qualify for issue of this document.
