Sri Lanka ETA vs visa on arrival - what is the difference and how do I apply correctly?

This is the most common question I get and the confusion is understandable because the terminology has changed. Let me explain clearly.

What the ETA is: the Electronic Travel Authorization (ETA) is the pre-approval required for most nationalities before travelling to Sri Lanka. It is applied for online at the official government website (eta.gov.lk) and approved electronically — you do not get a stamp or sticker, just an approval email. You show this at the immigration desk along with your passport.

Cost and validity: the standard tourist ETA costs USD 35 (or equivalent) for double-entry and is valid for 30 days per entry, extendable once in-country for a further 30 days through the Department of Immigration. Single-entry is also available at a slightly lower cost.

Who can get it: most nationalities including those from South Asia, Southeast Asia, Europe, North America, and Australia apply via the ETA system. A small number of nationalities (mainly Maldivian, Singaporean, and a few others) receive free visa-on-arrival.

Bangladesh specifically: Bangladeshi citizens are eligible for the ETA but should check the current list on eta.gov.lk as this can change. Apply at least 3-5 days before travel — approvals are usually very fast (often within hours) but do not leave it until the night before.

Third-party sites: the official URL is eta.gov.lk (Sri Lankan government). Many commercial websites mimic the official site and charge USD 50-100+ for the same ETA by adding a service fee. They are legal but unnecessary. Always use the official site directly. Pay close attention to the URL.

At the airport: immigration officers will ask to see your ETA approval email on your phone or printed. Have it accessible before you join the queue.
