The term for the migration of people into a new country is "immigration." This process involves individuals or groups moving from one nation to another with the intention of settling there, often in search of better economic opportunities, safety from conflict, or to join family members. Immigration can significantly impact both the host country and the individuals migrating, leading to cultural exchanges and economic growth. While immigration has historically shaped nations and societies, it can also be a controversial topic, often sparking debates about border control, citizenship, and social integration.
