I wonder what's up with the huge spike in 1991. Gulf War? Collapse of the Soviet Union? Or just coincidence?

(Incidentally, my parents moved to America the year after, in 1992. I guess the early 90s were a particularly popular time to come to America.)

I'm not sure. Reagan signed an immigration amnesty act in 1986 which made millions of illegal immigrants eligible for permanent legal immigration. Perhaps it took a few years for the applications to go through.

That dip during WW2 is pretty grim, given that the US was turning away boatloads of Jewish refugees at the time.
