What does immigration mean?

Moving out refers to moving in, and the so-called moving in refers to holding a green card of the country and belonging to a permanent resident of the country. Or join the nationality of that country and become a citizen of that country.

To settle abroad (emigrate) means that citizens of one country go to another country or region for permanent residence through various channels, that is, to settle down. Going abroad to settle down is an international movement of people across national boundaries, also known as immigration or international immigration.
