Final answer:
Immigrants are individuals who move permanently from one country to another for various reasons, including economic opportunities, political persecution, or family unification. Illegal immigrants enter or stay in a country without authorization, creating complex challenges. Immigration has profoundly impacted economic and cultural landscapes, especially in the U.S.
Step-by-step explanation:
Immigrants are people who move permanently from one country to another. They are different from migrants, who may move seasonally or temporarily. The act of leaving one's country is called emigration, and upon arriving in a new country, one becomes an immigrant. Immigrations encompass a variety of circumstances, including escaping from political oppression or war, seeking economic opportunities, or joining family. Illegal immigration occurs when individuals enter or remain in a country without official permission, which can lead to complex socio-economic issues.
Throughout history, immigration has been a driving force for economic growth and cultural change, particularly in the United States. Labor migration is another form of movement, where individuals relocate primarily for employment purposes. However, immigrants and migrants also include those fleeing war or persecution, often referred to as refugees. The U.S. continues to be a destination for people desiring improved quality of life, with initiatives such as the DREAM Act and DACA providing pathways for undocumented individuals to achieve legal status.
