Student Visa :
A special endorsement that is added to a passport that governments issue to students who are enrolled at qualified educational institutions. Student visas are non-immigrant visas that do not require the holder to obtain citizenship. Any prospective student seeking higher education in another country must obtain a student visa for that country.
Most countries will issue student visas in order to allow foreign students to attend school within their borders. However, in most cases the student must be enrolled at a postsecondary institution of higher learning. Foreign exchange students must therefore usually obtain a different type of visa, such as for temporary residence.
Travel visa /Tourist Visa :
A visa is a conditional authorization granted by a country (typically to a foreigner) to enter and temporarily remain within, or to leave that country. Visas typically include limits on the duration of the foreigner’s stay, territory within the country they may enter, the dates they may enter, or the number of permitted visits. Visas are associated with the request for permission to enter a country and thus are, in some countries, distinct from actual formal permission for an alien to enter and remain in the country. In each instance, a visa is subject to entry permission by an immigration official at the time of actual entry and can be revoked at any time.
A tourist visa generally gives non-citizens clearance to enter a country and to remain there within specified constraints, such as a time frame for entry, a limit on the time spent in the country, and a prohibition against employment. Some countries do not require a visa in some situations, such as a result of reciprocal treaty arrangements. The possession of a visa is not in itself a guarantee of entry into the country that issued it, and a visa can be revoked at any time.
A visa application in advance of arrival gives the country a chance to consider the applicant’s circumstance, such as financial security, reason for applying, and details of previous visits to the country. A visitor may also be required to undergo and pass security and/or health checks upon arrival at the border
Types of Tourist Visa :
1. Family visit : Visa to visit family member, relative or to attend any event falls under this category.
2. Tourism : Visa to explore the nation comes under this category.
Permanent residency :
Permanent residency refers to a person’s visa status: the person is allowed to reside indefinitely within a country of which he or she is not a citizen. A person with such status is known as a permanent resident. Not every country necessarily has a facility for someone to be a ‘permanent resident’. Rights and application may vary widely.
