Important Notes for Regular Tourist Visa
Today India has also become accessible to travelers looking for a last minute holiday getaway and to those who may not have considered traveling to India in the past.
Passport holders of below listed countries will be able to apply and pay for an online visa using the Indian government's tourist visa website, removing the need to book an appointment at the outsourced visa processing agency, or make a laborious postal application.
The ability to apply online from home would be "far quicker and easier" and it would also enable people to apply for visas nearer to the date of departure.
The cost of eVisa (Visa on Arrival) is USD 60 (£39), and rather than book an appointment at an application center or provide documents in the post, applicants will now be able to upload documents, pay the balance and track their application online. However applicants could expect to pay a processing fee of USD 1-2.
Visas will still not be issued immediately - once an online application is submitted, travelers can expect to receive entry documents via email within four days. But it is an improvement on the previous arrangements, which saw a typical postal application take up to two weeks.e-Tourist Visa (Visa on Arrival) Facility is available for holders of passport of following countries/territories**
