Sri Lanka Visa
For entry into Sri Lanka (or Ceylon as it was once called) you require an ETA (electronic visa). These were very easy to get even fro Aida $20 from the website. Approval was given in a matter of minutes. So for Iranians, Sri Lanka is an easy country to get in compared to some in Asia, no visits to Embassies.
Fill up the form, make the payment and in few hours you will get the approval email. Done
