Syrian Americans are Americans of Syrian descent or background. Syrian Americans may be members of a number of differing ethnicities, including Arabs, Armenians, Arameans, Assyrians, Syrian Jews, Kurds, Syrian Turkmens and Circassians. It is believed that the first significant wave of Syrian immigrants to arrive in the United States was in 1880. Many of the earliest Syrian Americans settled in New York City, Boston, and Detroit. Immigration from Syria to the United States suffered a long hiatus after the United States Congress passed the Immigration Act of 1924, which restricted immigration. More than 40 years later, the Immigration Act of 1965, abolished the quotas and immigration from Syria to the United States saw a surge. An estimated 64,600 Syrians emigrated to the United States between 1961 and 2000.
