The most dramatic case is that of the Central Americans. Why are people fleeing Central America? It's because of the atrocities the U.S. committed there. Take Boston, where there's a fairly large Mayan population. These people are fleeing from the highlands of Guatemala, where there was virtual genocide in the early 1980s backed by Ronald Reagan. The region was devastated, and people are still fleeing to this day, yet they're sent back.
