Just an FYI. Since you've tagged this list with aliens, it's showing up under the Science Fiction > Aliens genre.

My vote is for Tortilla Curtain. Here's a post about Tortilla Curtain's relevance to the current immigration reform debate: http://newsworthynovels.blogspot.com/...

How are we defining "immigrant" here? I was surprised to see Hotel on the Corner of Bitter and Sweet, since the protagonists were Japanese-Americans, born in the USA. It's an awesome book, but I am concerned about the political point of labeling the main characters exactly the way the US government did back then.

Another one: Chinua Achebe's No Longer At Ease is NOT an immigrant story. I don't want to mess with the contributions if Jessica is still here and active, since she started it. But it should be recognized that not everyone who comes to the USA, UK, or other western countries prefers to live in the USA or other parts of the West, and in the case of Achebe's protagonist, he goes to England, gets his education, leaves to go back to Nigeria. Thousands if not more do this very thing every year. A person who lives in the UK,US or elsewhere for a limited time, and with a limited purpose, is not an immigrant, they are a visitor. This touches a personal chord for me, because I am married to a citizen of another country who lives in the USA, and well-intended people are constantly trying to hyphenate my spouse with "-American", and repeatedly we have to say, "Actually, no." There is a bias to the assumption that whoever sets foot on these golden shores must SURELY want to stay here forever.

Removed for not being about the immigrant experience/author spamming:
The Girls on Rose Hill
Unsavory Elements: Stories of Foreigners on the Loose in China
The Farther I Walk, the Closer I Get to Me b. Hong Mei

Hm. Bless Me, Ultima is on here, but it's most certainly not about immigrants or even immigration. Do people just assume that because it's about Spanish-speakers in New Mexico they immigrated there? They were there before it became part of the US...

Wow, there are sooo many books on this list that just do not belong by any stretch of the imagination. O.o

How to Raise Confident Multicultural Children

I understand why there are so many votes for Roots, but "immigrant" isn't the right descriptor there.
