Immigration in Chile: Causes and Consequences

Immigration is the international movement of people that has always existed (since the establishment of borders) and is driven by various causes, such as wars, seeking work, or improving the quality of life. In Chile, the primary motivation for immigrants is the pursuit of better job opportunities and an improved quality of life, benefiting not only themselves but also their relatives in their native country.

Immigration yields numerous consequences. In my opinion, the benefits generally outweigh the drawbacks, provided the receiving country is adequately prepared to manage the phenomenon. Below, we briefly examine the key benefits and challenges of immigration in Chile.
