Visa policy is like getting a permission slip to enter another country. So, if you want to go to India, you need a visa. It's like a special ticket that says you are allowed to be in India for a certain amount of time.
India has different types of visas for different types of people. Some visas are for tourists, some are for business people, and others are for people who want to live in India for a longer time.
To get a visa for India, you have to fill out some forms and provide some information, like your name, passport information, and the reason why you want to go to India. You may also need to provide some proof of where you will live in India and how long you will stay.
The Indian government decides who can come to India and who can't. They have their own rules and regulations about who can get a visa and who can't. Sometimes they may also ask for more information or even deny you a visa if they think you don't meet their requirements.
So, getting a visa to go to India may seem complicated, but it's just like getting a permission slip from your teacher to go on a field trip. You just have to follow the rules and provide the right information to get your visa.
