Other than Mexican? Deportees, 1911
At some point, I decided the book I’d started (and abandoned, and restarted and abandoned… and have more or less in the editing process now) was about the effects of foreigners on Mexico since 1524. I’m not writing any sort of “magnus opus” or anything particuarly in-depth, but I was bothered by the lack of information on one of the more important immigrant groups in Mexico… the Chinese.
Just to dump the few notes I had, I set up a quick and dirty blog, hoping someone would pick it up. Someone has.
Scott Parks’ “Chinese in Mexico” is a nicely done site, well worth a visit, and well-worth adding the bits and pieces anyone is able to find on an otherwise nearly unknown story of the Americas.

Back then, border crackdowns focused on Chinese and other foreigners barred from entering the United States — not on Mexicans and other Latinos.
