Jason Richwine calculated the Wechsler Digit Span IQ subtest scores for different immigrant groups from it, but nobody has yet published the IQ scores from the four Woodcock-Johnson III IQ subtests given to 3 to 12 year-old children of immigrants with legal permanent residency in the NIS.
You'd have to be careful in evaluating the scores, since on most of the subtests, between 25-50% of the kids got scores of zero. Presumably, they were utterly defeated by language problems due to the Woodcock-Johnson IQ test not having been translated into their exotic language. They should be left out. (In contrast, the very simple Wechsler Digit Span subtest was translated into a huge number of languages. One immigrant's child took it in Amharic.)
However, 704 of the Woodcock-Johnson tests were given in Spanish, so those scores are probably more or less fair. And you'd also need to work on how to convert Woodcock-Johnson scores to IQ scores.
It would be an ambitious project, but a significant one.
