Can you believe it? It's more notes on Migration!

    I'm just going to get straight into the notes today so... Countries adopted selective immigration policies after the Quota act of 1921 and the National Origins Act in 1924. These laws marked the end of unrestricted policies. Family reunification makes up for 3/4 of immigrants in the U.S., and skilled workers make up 1/4 of immigrants. Diversity in migration is when a country that doesn't send many migrants sends some. The source country for 58% of immigration in the U.S. is Mexico. Out of the 11.2 million illegal immigrants 1 million are children. In 2010 35% of adult migrants had been in the U.S. for at least 15 years. Texas and California have the largest number of unauthorized immigrants.
