Okay kiddo, let me explain what an electronic system for travel authorization means. When people want to travel to the United States, they usually need to fill out an application to get permission first. This application is called an ESTA, or electronic system for travel authorization.
Now, ESTA is a fancy way of saying an online form that you fill out to ask for permission to travel to the US. It's like asking your mom or dad for permission to go somewhere, but you're asking the US government instead.
When you fill out this form, you need to provide some personal information about yourself, like your name, where you live, and your passport number. The US government then uses this information to make sure that you're not a security risk or a threat to the country.
Once you fill out this form, you'll usually get a response right away. You might get approved, which means you can travel to the United States. Or you might get denied, which means you can't go there.
So, that's basically what an electronic system for travel authorization is. It's just an online form that you fill out to get permission to travel to the US. I hope that helps!
