I speak English only and I had no trouble getting in to UTHSCSA. Look on the website, they have a formula that they use to determine acceptance. The TX schools are all about DAT GPA and interview, simple as that. I was not in a predental society, did no research and I still got first round acceptances to all three schools. This sounds like I'm being a bit of an ass, but I would only worry about GPA and DAT and if it's too late for that, focus on your upcoming interviews. They don't really care all that much about your extra cirriculars or what school you attended(I went two years to a Community college and 2 two to the University of Arkansas). So, to answer, being bilingual won't help you unless you're on the waitlist and it's down to you and bilingual person your stats are both tied.
