<p>You cannot become a resident for instate tuition by attending school for a year. There would be no OOS students if that was the case. Make sure you check the rules with the school if remaining OOS is going to make it impossible to stay at the school.
Requirements for Resident Status:</p>
<p>The general rule is that in order to obtain resident status for tuition purposes, a student must</p>
<ol>
<li>Demonstrate US citizenship, Permanent Residency or legal immigration status;</li>
<li>Establish their legal domicile in Arizona for at least one year immediately proceeding the last day of registration for the semester for which the student proposes to attend the University.</li>
</ol>
<p>In general Arizona domicile occurs when a financially independent person has been physically present in Arizona for at least a year with the clear and convincing intention of making Arizona their permanent home beyond the circumstance of their being a student.</p>
<p>Please note that the Arizona Board of Regents Policy states:</p>
<ol>
<li>That the domicile of a minor is that of the minor’s parent.</li>
<li>That all evidence presented in support of in-state residency be weighted under the presumption that a non-resident student’s presence in Arizona is primarily for the purpose of education and not to establish domicile. Decisions regarding residency are to presume, barring clear evidence to the contrary, that no emancipated person has established a domicile in this state while attending any educational institution in this state as a full-time student.
