As part of my Project Assignment I have been staying in Oman quite long time. Just to take a break from my daily 9 to 5 life, planned for short Sri Lanka (SL) trip.
As we didn't have much time to research about our destination, so we have opted for tourist agent (www.visitsrilankatours.com). SL has Electronic Travel Authorization (ETA) process for tourist Visa. Applied for the same using (www.eta.gov.lk) online, had to pay 20 $ each. We had received a acknowledgement post to our payment (Within 24 hrs.), which will be sufficient enough for on arrival VISA stamping.
SL culturally quite similar with South India, specifically to Chennai (India). Almost 70% population believes in Buddhism. They talks mostly in Sinhala, Tamil and English.
