There are a few exceptions: some medical schools in more rural states have preferences for in-state students who plan to stay in-state.

<p>I wouldn't say it's just a few exceptions. As stated by ohnoes has said, almost all public professional schools favor in-staters to some extent.</p>
<p>For example, consider this blurb from UCSF, which is arguably the best public med-school, and the best overall med-school on the West Coast. </p>
<p>"Does UCSF School of Medicine give preference to California residents?</p>
<p>Yes. The Committee on Admissions gives preference to California residents, who make up about 80 percent of the entering class annually."</p>
