What are visa rules?

Visa rules are like tickets that let people travel from one country to another, just like you need a ticket to ride the bus or go on a fun trip.

Imagine you're playing with your friend, and they want to come over to your house to play. But their parents need to know if it's okay for them to stay. That’s kind of how visa rules work. If someone wants to live in another country, maybe for a while or even forever, the visa is like a special permission from that country.

Some countries let people come without needing a ticket at all, it's like getting a free pass! But others need you to fill out a form, show your money, or even talk to an officer. These are the rules each country sets up, and they help decide who can come in and how long they can stay.

There are many kinds of visas, like one for work, one for school, and even ones just for visiting friends! Each has its own set of rules. It’s like having different kinds of tickets for different kinds of trips.
