code-switching between Cantonese and Vietnamese to speak to both Hoa immigrants from Vietnam and ethnic Vietnamese. Teochew, a variety of Southern Min which had virtually no speakers in the US before the 1980s, is spoken by another group of Hoa immigrants. A small number of Vietnamese Americans may also speak Mandarin as a third (or fourth) language in business and other interaction. Eurasians and Amerasians Some Vietnamese Americans are Eurasians: people of European and Asian descent. They are descendants of ethnic Vietnamese and French settlers and soldiers (and sometimes Hoa) during the French colonial period (1883–1945) or the First Indochina War (1946–1954). Amerasians are descendants of an ethnic Vietnamese (or Hoa) parent and an American parent, most commonly white or black. The first substantial generation of Amerasian Vietnamese Americans were born to American personnel, primarily military men, during the Vietnam War from 1961 to 1975. Many Amerasians were ignored by their American parent; in Vietnam, the fatherless children of foreign men were called con lai ("mixed race") or the pejorative bụi đời ("dust of life"). Since 1982, Amerasians and their families have come to the United States under the Orderly Departure Program. Many could not be reunited with their fathers, and commonly arrived with their mothers. In some cases, they were part of false families that were created to escape from Vietnam. Many of the first-generation Amerasians and their mothers experienced significant social and institutional discrimination in Vietnam, where they were denied the right to education; discrimination worsening after the 1973 American withdrawal, and by the U.S. government, which discouraged American military personnel from marrying Vietnamese nationals and frequently refused claims of U.S. citizenship that were lodged by Amerasians born in Vietnam if their mothers were not married to their American fathers. Discrimination was even greater for children of black servicemen than for children of white fathers. Subsequent generations of Amerasians (children born in the United States) and Vietnamese-born Amerasians whose American paternity was documented by their parents' marriage or their subsequent legitimization have had an arguably more favorable outlook. The 1988 American Homecoming Act helped over 25,000 Amerasians and their 67,000 relatives in Vietnam, to emigrate to the United States. Although they received permanent-resident status, many have been unable to obtain citizenship and express a lack of belonging or acceptance in the US because of differences in culture, language and citizenship status.
