For a Short Visit to Sri Lanka, travellers should obtain an ETA with effect from 1st of January 2012. On the basis of reciprocity, citizens of The Republic of Singapore, The Republic of Maldives and The Republic of Seychelles are exempt from the requirement of obtaining ETA to visit Sri Lanka. The issuing authority of the ETA is the Department of Immigration & Emigration, Colombo, Sri Lanka. Persons intending to visit Sri Lanka can apply for ETA online. In addition to this option, an applicant may also go for one of the alternative options. (For more info...) Diplomatic and Official passport holders are exempt from ETA processing fee, only when their applications are submitted through the state agencies such as Ministries, Statutory Bodies, Sri Lanka Overseas Missions etc. The ETA is initially limited to 30 days validity from the date of arrival although it may be extended for up to six (06) months.
