What is defined as the process of relocating from one country to another for residence and work?

The correct answer is immigration, which specifically refers to the act of moving to a foreign country for the purpose of establishing residence and often seeking employment there. This process involves individuals entering a new country with the intent to live, work, or perhaps even integrate into society.

Emigration refers to the act of leaving one’s own country to settle in another, which is the opposite of immigration. Migration is a broader term that can encompass both emigration and immigration, as well as movement within a country or to a different area. Refugee relocation deals with the specific situation of individuals who are forced to flee their home country due to persecution or violence, rather than a general process of relocating for work and residence.

By understanding this distinction, one can see that immigration is specifically focused on the movement into another country for the purposes noted in the question.
