Just as there are different stages of change in Canada, immigrants have experienced various stages of change. Changes in postwar immigration have had a major impact on today's social and immigration patterns. These changes include a post-war immigrant boom, a decline in independent immigration laws, and an increase in multiculturalism and refugee immigration. Since the size of immigrants and the source of immigrants have brought dramatic changes to the "face" of Canada, postwar immigration models are different from previous immigration waves.
Let the students attract immigrants from the recent immigration era. "Old" immigrants of the previous civil war and "new immigrants" after the civil war. What are similarities and differences? What are the social responses that these immigrants face? The theme trend of the whole period? What are the characteristics of individual eras and immigration groups?
After the Second World War, immigrants were mainly the result of the postwar refugee movement, and in the 1950s and 1960s the colonization of Asia and Africa was over. Immigrants from these areas to the former imperial centers such as England and France are increasing. For example, in the UK, in 1948 the British Nationality Act gave the former citizenship of England to the citizens of the former British colonial territory (perhaps to 800 million people).
Since 1945, immigrants in America have been far from the number of immigrants from the 20th and early 19th century American immigrants, especially from Asia. Since the end of the 19th century, the US government has taken steps to ban emigrants from Asia. The nationality quota system established by the immigration control law in 1924 narrowed the entry of people in eastern and central Europe and made Western Europe the main source of entry and departure. These policies form the ethnic and ethnic identity of Americans before 1945. Signs of change began to appear during and after World War II. The recruitment of temporary farmers from Mexico brought influx of Mexicans and the abolition of Asian exclusion law opened the doors for Asian immigrants. After immigration reforms finished the citizen allocation system in 1965, the flow of people to the United States dramatically increased.
