What is considered 'immigration'?

The definition of immigration primarily focuses on the act of moving to a new country with the intention of establishing long-term residence or settlement. This process involves individuals leaving their country of origin to create a new life in another country, influencing various aspects of both the home and host countries, such as demographics, economy, and culture.

Understanding immigration also involves recognizing that it typically reflects a deeper commitment than temporary visits. While the other concepts listed pertain to travel and business relocations, they lack the characteristic intention of establishing new roots in a different country that defines immigration. This distinction is essential to grasp the broader sociological implications of immigration on society, including integration, cultural exchange, and economic impacts.
