In the 1960s, South Koreans immigrated to the United States in search of family reunions.
The 1965 Immigration and Naturalization Act ended the national quota system and made it possible to reunite families.
The annual number of Korean immigrants has steadily increased since 1965, reaching 30,000 in 1976.
These Korean immigrants were white-collar workers in Korea who came to America freely, unlike the first and second waves of immigrants, who were largely laborers, war victims, or political refugees who had little choice but to immigrate.
Therefore, option (a) or (ii) is the correct answer.
