@iDOliveinMD...UT Austin will be competitive just because of location and name alone. UT Rio Grande Valley probably won't be (it's located on the Texas/Mexico border...although South Padre is close!). Although you'd need a compelling reason to want to attend, they will prefer Spanish-speaking students/primary care interested students. At least...this is the gist I get from their website. However, if you have a 30+ MCAT and 3.6 gpa and up I'm sure your oos-ness won't matter as much (think of it this way...would they rather accept 27, 28, 29s from Texas or 27, 28, 29s from oos?)
Good luck!
