International migration means when people move from one country to another country to live there permanently or for an extended period. It's like moving from your house to a new house, but instead of just going to another street, you are going to another country.
People migrate to other countries for lots of reasons, such as to find a better job or to be with their family members who live in another country. But migrating to a new country is not always easy because there can be many rules and regulations that people have to follow.
Before moving to another country, people have to get special permission from the government of that country, and they have to follow many rules to enter that country. There may be laws about what kind of work they can do, and they may need to learn a new language. They also have to find a new home to live in, make new friends, and learn about the new place they are living in.
People who want to migrate to another country usually take a long time to plan and prepare for the move. They need to pack all their things, say goodbye to their friends and family, and sometimes even sell their house or car. It can be stressful and emotional to leave everything behind and start over in a new place.
Finally, when people arrive in their new country, they have to work hard to adapt to their new home. They must learn new customs, traditions, and ways of living. They will often find that life in their new country is very different than their life in their old country. But with time, patience, and the willingness to learn new things, they can make their new home a happy and fulfilling place to live.
