UT Priority Application?

Please help! So, I’m confused as to whether or not I can apply priority. On the school website there are clearly two deadlines: a priority one and a regular one. You can see it here: https://admissions.utexas.edu/apply/freshman-admission

However, when I am in the ApplyTexas application, there is only an option to apply regular decision. It says:
“Please select a deadline for your application to The University of Texas at Austin.” And then there is only one option that says “The regular deadline for U.S. Freshman applications (12/01/2017)”.

Does that mean there is no option to apply early? If so, then why is there a priority deadline on the website? Is that option only available for Texas residents or something? Any help is greatly appreciated.

There is no early admission at UT. UT sends out the first round of letters indicating acceptance to your major in November to a few students who UT really desires. In order to be considered for that round you need to have your application in by November 1st or the priority date. Also, if you are trying for honors, I would get your application in by November. The vast majority of students receive notification in February.
