It is possible to apply for an Electronic Travel Authorisation (ETL) to Sri Lanka online.
Roughly how long does it typically take for an ETL to be issued once the application has been made?
In case it makes any difference, I am an Australian citizen looking to obtain a 30 day tourist visa. Everything should be straight-forward.
It was practically instantaneous for my wife and when we applied a year ago. I submitted the online application on 28 January 2013 21:05 and received the approval on 28 January 2013 21:10, and my wife had an identical experience. We were also applying for a 30 day tourist visa.
In case you think nationality might be relevant (it could be): We were both travelling with Irish passports, flying in from Chennai, India.
