Vietnamese-Americans immigrated to the United States in different waves. The first wave of Vietnamese from just before or after the Fall of Saigon/the last day of the Vietnam War, April 30, 1975. They consisted of mostly educated, white collar public servants, senior military officers, and upper and middle class Vietnamese and their families. The second wave came in the 1980s escaping very precariously in boats from the communist regime as boat people. In the 1990s and 2000s, a third wave came from the US's Humanitarian Operation Program, family members of Vietnamese Americans, former prisoners of re-education camps, and Amerasian children of American servicemen who applied for entry into the United States. Vietnamese Americans vary in income level, with some being upper-class while others, particular those who came later, are working-class.
