Obtaining authorization for entering a country:
Possession of the visa is not necessarily a guarantee of entering the country that issued it; it can be revoked any time. The visa process allows the issuing country to scrutinize the identity of the applicant before entry is permitted. Some visas are granted by prior application to the countries consulate or embassy or on arrival or through private visa services that specialize in issuance of travel documents. These agencies have the authorization of embassies/ consulate or foreign agencies to represent travelers who are unwilling or unable to visit the embassy to apply in person.
Visas for Australia provide a specialist service intended for persons seeking to travel for either business or tourism. Visa applications depend on the purpose and duration of the visit. There are different categories of visas available for persons intending to visit Australia. The different visas cater for migrants, workers, employers, visitors, students and refugees. Each of the visas provides specific requirements and obligations.
Australians do not generally require American visas for temporary visits. However, an ESTA clearance is necessary. Plans for a longer stay including study or work related visits require an American visa. US Visas are issued to foreign citizens seeking to travel the United States of America before travelling. The US Visa grants permission to the applicant to travel to a possible port of entry, land border crossing or airport and request for permission of customs, Boarder Protection inspector and Department of Homeland Security to enter the United States. The visa does not however give non- citizens rights, including rights to enter the country or to stay in the country. The purpose of the travel prescribes the type of visa. A non- immigration visa is obtained for a temporary visit while the immigration visa is issued for permanent stay.
Citizens of other countries seeking to travel to India are advised to make their applications for Indian visas regardless of the nature of visit. The main categories of visas are Temporary India Visas (i.e. tourist visa, business visa and transit visa) and Permanent India Visas.
Working Holiday Visas depend on the country expected to be visited. Australian nationals wishing to travel to specified countries must endeavor to abide by the provisions of the embassy or consulate of the country of destination, to qualify for working holiday visas. It is equally important for applicants to consult with embassies or authorized immigration service of the country on possible work related travel plans before embarking on the journey.
