Hi,
I'm currently in between MS I and II down here in Ponce, let me know if you have any other questions...
As far as I know, residency programs look favorably on bilingual applicants, but I would honestly say that you would have a much better chance at the East coast residencies than the West coast, since many programs west of the mississippi have not even heard of Ponce. We're trying hard to remedy that situation, but its been slow going. The MCAT is scaled for PR residents, so anything above a low-20's for a bilingual mainlander is ok according to the adcom, and they will consider you for acceptance, especially with an average(for the US, ~8) verbal score. Take care and good luck.
