- VISA is a necessary document to travel in certain countries. That is why it is important to check if a country you're about to visit requires a VISA or not. But there are other countries such as: Brazil, Cambodia, Fiji, Indonesia, Israel, Peru, Singapore, Sri Lanka, Taiwan, Thailand, Vietnam, and other related countries. There is no need to prepare any documents if a country doesn't require a VISA to enter.

- There will also be other countries that require other certain countries to obtain a VISA to enter. For example: India requires Filipinos from Philippines to have a VISA to enter, but it doesn't require other countries like in Ameria to have a VISA to enter.

- Each country has their own VISA. Having an Indian VISA doesn't mean you have access to Korea, you will still need a Korean VISA.
