Difference between emigration and immigration

To migrate is to move from one country, or place, to another.

1. To emigrate (Latin emigratus 'migrate out') is to leave one's own country to settle in another.
2. To immigrate (Latin immigro 'migrate in') is to come as a permanent resident to a country other than one's native land.

...so one country's emigrants are other countries immigrants.

we emigrate from, and we immigrate to,that is the difference
