It may not be accepted, but I would at least check to see if they would entertain a truly nonverbal IQ, such as the Leiter-3. That is the measure of choice that I give in my assessments when the child is not proficient in English. The DAS, WPPSI, and SB's nonverbal indexes will still put your child at a disadvantage as they still rely on some language (receptive).
The Leiter is entirely visual-spatial and again, nonverbal (receptive and expressive). I'd caution that it might not be sufficient for your needs, but I know that it is becoming more commonly given in the school districts in my area when language is a concern (bilingual with other language dominance, language disorder, etc)
