During ancient times the geographical boundaries of nations were not demarcated and human beings were free to travel from one place to another without any official restriction. However the world has changed and one needs to have prior approval of the relevant authorities in order to gain access to the areas of another country. The prerequisite for applying for a visa is the possession of a valid passport without which it's nearly impossible to travel all around the world. The same set of conditions are applicable for India too. Apart from having a valid passport a person needs to get authorization from the relevant authorities allowing his/ her stay in that particular country. This authorization is formally termed as e-Visa. With changing times lots of countries have gradually shifted to e visa as it is accessible from the comfort of the homes of the international visitor. India also began services of evisa for India in the year 2014. In the beginning this facility was limited to a few countries only but have been gradually extended to several other countries as well. Citizens of Nepal and Bhutan need not apply for a visa to enter India. For a limited group of countries there are facilities for evisa on arrival too.
Evisa for India facilities which were previously known as electronic travel authorization services has been a landmark project of the Indian government. The e-visa facilities have been further categorized into e tourist visa for India, e business visa for India and e medical visa for India. The validity of the e visas for India is 60 days. Maximum of 2 entries is allowed on e business visas and e tourist visa while 3 entries are allowed per visa approval for the E medical visa for India.The duration of visit cannot be extended and a maximum of two visa approvals are made per calendar year. The international visitors are not allowed to access the restricted and sensitive areas. Tourists of Pakistani origin are not eligible for this e visa for India scheme and they need to apply directly in their particular High Commission for eVisa approval. The international visitors need to apply at least 4 days prior to their arrival to India. They should also have their return tickets as well as enough money to comfortably stay in the Indian Territory in order to get approval for their e-visa for India. International visitors can gain entry to India through the help of these e visa approvals at around 24 airports and 3 seaports and gain exit from any airport of their choice.
