The documents you need for your Tourist Visa are:
A completed Arrival Card.
A completed Online Visa Form.
The Online Visa Form can be filled prior to your arrival by visiting the Department of Immigration official website [link]. Or you can fill it up using Kiosk machines upon your arrival at the airport. If you will it from the website, you will get a submission confirmation and a receipt with barcode. You are required to print the receipt and bring it along on your trip.
