Final answer:
Koreans succeeded in immigrating to the United States by taking advantage of the Refugee Act of 1980, seeking better economic opportunities, and benefiting from U.S. immigration policies that favor skilled workers and those from communist nations. They also tapped into niche markets such as the African-American hair-care product industry due to advantageous trade policies and strong community networks.
Step-by-step explanation:
Koreans have utilized various avenues, including the Refugee Act of 1980, to successfully immigrate to the United States. The Act provided a basis for those fleeing from politically unstable environments in Asia, such as Vietnam and Korea, to find resettlement opportunities. Furthermore, with the U.S. having a rich history of immigration and assimilation, Korean immigrants have sought better economic opportunities and the promise of the American dream, factors that are embodied by U.S. culture promoting values like freedom and affluence. Additionally, U.S. laws have evolved to encourage the immigration of individuals from communist nations and those with valuable skills, such as healthcare professionals and engineers. On the economic front, some Korean immigrants have entered specific industry sectors largely through established familial and business networks, such as the hair-care product industry that caters to the African-American community.
