Please note that after 31st December 2011, all U.S. nationals expect to visit Sri Lanka have to apply visa online through ETA (Electronic Travel Authorization) system. A processing fee of $30 will be charged from the applicants. The passport should be valid for at least six months from the date the visa is to be issued. 2  Business visa applications should accompany a letter from the sponsoring agency in Sri Lanka, a letter from the employing company in US and a copy of onward â return air ticket and travel itinerary.
Exceptions include American citizens and visitors with a valid visa. ItÂ´s best to get your ETA before you book your flight to Canada. You may not be able to fly without it. In most cases, the ETA will be granted within minutes of applying. Once approved, your ETA is valid for five years or until your passport expires, whichever comes first. This means you can fly to Canada without reapplying so long as your ETA and passport remain valid. To make sure that you can board your flight to Canada, you will need to travel with the passport you used to apply for your ETA as the ETA is electronically linked to it. If in doubt, you can always check the status of your ETA on Canada.ca/eTA. To find out more, including who needs an ETA and who doesnÂ´t, visit Canada.ca/eTA. See you in Canada!
