Any Foreign eligible individuals that are planning to visit Sri Lanka are able to complete a short and easy online e-Visa application form for travelling to Sri Lanka for tourism purposes.
This online process for e-Visa for Sri Lanka was implemented towards the 1st of July of 2016 by the Government of Sri Lanka, with the goal of enabling any of the future eligible travellers to apply for an e-Visa to Sri Lanka.
The Sri Lankan visa website lists the countries that are eligible for e-Visas. Applicants must also have a valid passport with at least 6 months of remaining validity.
The visas permit stays for up to 30 days and are valid for 3 months (so you can do multiple visits).
