Historically, the United States has experienced waves of immigration from various ethnic groups throughout the years due to push and pull factors. During the 1970s
immigration from Asia increased dramatically to the U. S. Using the passage above, what
best might explain this increase?
The 1965 Immigration & Nationality Act abolished the restrictive national origins system
originally passed in 1924 in favor of a quota and preference system. Priority was now
given to "family reunification" so that U. S. citizens and permanent residents could sponsor
the following types of immigrants in this order of preference:
1. Unmarried children under 21 years of age of U. S. citizens
2. Professionals, scientists, and artists "of exceptional ability"
3. Siblings and their spouses and children of U. S. citizens
4. Workers in occupations with labor shortages
5. Political refugees
