1) How and why have millions of people moved from Asia to the United States since the 1960s? 2) What events and issues have rallied Asian Americans...

Asian
immigration to the United States has occurred largely for the same reasons that immigration from
other areas has.  Asians have come to the US because they have wanted to escape bad conditions
in their own countries and because they have been attracted by better conditions in the US. 
With regard to Asians in particular, immigration has increased since the 1960s because a law
passed in 1965 removed the legal barriers to Asian immigration that had previously existed. 
Once these barriers were removed, more Asians came.  Vietnamese fled the conflict in that
country.  Koreans and Filipinos came for economic opportunities.  These are typical reasons for
immigrants to come to the US.

There have not been many events or issues that
have rallied all Asian Americans over the past four decades. ...
