The question of who can live in America is one that a lot of people are talking about these days. Have you ever looked at a map of the world? Countries come in all different shapes and sizes, and every country across the world has a border that separates it from other nations. Some countries are separated by natural borders like mountain ranges or rivers. Borders can also change over time, especially in times of war, or when different regions agree to change their borders. For example, the USA now has 50 states, but that wasn’t always true. The states were once separated, but they joined together over time to make a union.
The USA has two land borders. The northern border is 5,525 miles long, and it is with shared with Canada. The southern border, which is shared by Mexico, is 1,954 miles long. Every year, thousands of people cross from Mexico into the United States, and some people do it without permission from the US government. Some people say this is not a problem, and that Americans should welcome everyone who wants to come and live here, especially if they are poor in their home countries. On the other hand, some people think that too many people want to come and live in the US and that everyone should ask for permission before coming in.
President Trump has said that he wants to build a wall along the US-Mexico border to stop people from coming to the US without asking. Congress disagreed with him, so the president decided to use money from the military to pay for the wall. Some groups objected, so they went to court to stop the wall being built. Last week, the most powerful court in the country – the Supreme Court – said he could go ahead and use the money to start building the wall, after all.
