* The number of immigrants. The number of immigrants to the United States increased dramatically in the 1990s, from about 1 million per year in the early 1990s to over 2 million per year by the end of the decade. This increase was due in part to the Immigration Act of 1990, which increased the number of visas available for skilled workers and family members of U.S. citizens.
* The countries of origin of immigrants. In the 1890s, most immigrants to the United States came from Europe. However, in the 1990s, immigrants were more likely to come from Asia and Latin America. This change was due in part to the end of the Cold War, which led to an increase in immigration from Eastern Europe and the former Soviet Union.
* The reasons for immigration. In the 1890s, most immigrants came to the United States in search of economic opportunities. However, in the 1990s, immigrants were more likely to come to the United States for family reunification or to escape persecution in their home countries.
* The impact of immigration. Immigration has always had a significant impact on the United States, both economically and culturally. In the 1990s, immigrants played a vital role in the country's economic growth, and they also brought with them new ideas and perspectives that helped to shape American society.
In conclusion, immigration in the 1990s was different from immigration in the 1890s in terms of the number of immigrants, the countries of origin of immigrants, the reasons for immigration, and the impact of immigration.
