The first wave of Taiwanese migration to the United States involved mostly post-World War II immigrants from the area now ruled by China (Waishengren), most of whom were not Hakka. Later, the other Taiwanese people, whose ancestors arrived in Taiwan before 1945, including many Hakkas, started immigrating in larger numbers after the 1960s.
It is estimated that there are currently over 20,000 Taiwanese Hakka in the United States.
During the 1960s and 1970s, substantial migration of Jamaican Hakkas to the USA and Canada occurred. Most Chinese Jamaicans are Hakka; they have a long history in Jamaica. Between 1854 and 1884, nearly 5000 Hakkas arrived in Jamaica in three major voyages, with some of them subsequently going to the United States. Many of these people also have African ancestry.
A significant minority of early Chinese immigrants to Hawaii, and even fewer to the Continental US, were Hakka, and much of the animosity between the Hakka and Punti Cantonese people carried over. In the first half of the 1800s, around 30 percent of Chinese in Hawaii were of Hakka, while only about 3 percent in the West Coast were Hakka. There was a communal ban on intermarriages between the two groups for the first generation of migrants. In the middle of the 19th century, Hakka immigrants in America were excluded from membership in the Chinese organizations. The largest surge of immigration in that century occurred after an 1876 treaty between the US and Kingdom of Hawaii led to an increased need for labor.
Chinese revolutionary leader Sun Yat-sen lived in Hawaii for several years during his youth.
Many organizations have been formed to promote Hakka culture in the US. One group is the New England Hakka Association, which reminds its members not to forget their roots. One example is a blog by Ying Han Brach called "Searching for My Hakka Roots". Another group is the Hakka Association of New York, which aims to promote Hakka culture across the five boroughs of New York City. In the mid 1970s, the Hakka Benevolent Association in San Francisco (San Francisco Jiaying Association) was founded by Tu Chung. The association has strong ties with the San Francisco community and offers scholarships to their young members. The most prominent association in Hawaii is the Tsung Tsin Association (崇正會), which was founded in Honolulu in 1918 under the name Nin Fo Fui Kon (人和會館). It provides scholarships to US citizens in Hawaii that are preferably of Hakka background and/or interested in the Hakka culture.
The American Community Survey reported that 1,350 people in the United States speak Hakka at home. The actual number may be much higher because some respondents just filled out their response as "Chinese". Some Hakka Americans speak Mandarin Chinese or Cantonese instead.
