Marshall Islands is a group of small islands in the middle of the Pacific Ocean. If someone wants to visit these islands, they need permission from the government of the Marshall Islands. This permission is called a visa. Imagine a visa is like a special pass that you need to enter a big and fun playground.
Now, the visa policy of the Marshall Islands is like the rules of the playground. It tells you who can come to play in the playground and for how long they can stay there. For example, if you are from one of the countries that have a good relationship with the Marshall Islands government, you can easily get a visa to visit the islands. But, if you are from a country that has political problems with the Marshall Islands government, you might need to wait longer for them to give you the visa or even deny it altogether.
Also, just like there are different types of games you can play at the playground, there are different types of visas you can get to visit the Marshall Islands. Some visas allow you to stay for a short time, like a week or two, while others allow you to stay longer, like a few months or a year.
Overall, the visa policy of the Marshall Islands is like the rules of a big playground. It helps the government keep track of who is coming and going, and also ensures that visitors are safe and welcome on the islands.
