What is the difference between emigration and immigration ?

Emigration and immigration both refer to the movement of people from one country to another, but they have opposite meanings:

1. Emigration: It is the act of leaving one's country to settle permanently in another country. Emigration focuses on the country of origin, as individuals or groups are leaving that country and becoming residents or citizens of another.

2. Immigration: On the other hand, immigration refers to the act of entering and settling in a new country or region. Immigration focuses on the country of destination, as individuals or groups are arriving in a new country and becoming residents or citizens there.

In summary, emigration is leaving one's country to settle elsewhere, while immigration is moving to a new country to become a resident or citizen there.
