<p>I don't know how the process works in NC, but in VA, there are many hoops through which a student would have to jump to become a resident. Here, the aunt and uncle would have to become her primary guardian and she would have to reside in state for a certain amount of time (a year, maybe?). </p>
<p>There is usually an office that judges status at state schools and they're pretty quick to jump on cases that look iffy.</p>

Residency
Because we're a state-supported institution, we're required to determine whether or not each student is a legal resident of North Carolina. Because the laws governing residency can be tricky, and because residency applications are considered individually when a student applies for admission to the University, we offer the following as general guidelines.</p>
<p>Under North Carolina law, to qualify for in-state tuition for a given term for a given term you must prove:</p>
<pre><code>* that you established your domicile in North Carolina twelve months before the first day of classes for that term, and
* that you have maintained that domicile for at least twelve continuous months.
</code></pre>
<p>To prove that you've established a bona fide domicile in North Carolina, you must prove</p>
<pre><code>* that you were physically present in the state,
* with the intent to make North Carolina your permanent home indefinitely, and
* that you were not in North Carolina solely to attend college.
</code></pre>
<p>Because it's difficult to directly determine someone's intention to make North Carolina their home, we must evaluate actions taken that may indicate this "domiciliary intent." The following questions may be significant in helping us determine this intent:</p>
<pre><code>* Do you live in your parents' home?
* Where are/were you employed?
* Where did you register to vote?
* Where did you vote?
* Where have you served on jury duty?
* What are your sources of financial support?
* Where have you registered and/or licensed a car?
* Where did you get your last driver's license?
* Where do you own a home or other real estate?
* Where do you keep your personal property?
* Where do you list personal property for taxation?
* Where did you file state income tax returns?
* Where do you spend your vacation time?
* Where did you last attend high school?
* Where did you live before enrolling in an institution of higher education?
* Where do you maintain memberships in professional associations, unions, and similar organizations?
</code></pre>
<p>We weigh all the evidence furnished in an application for residence status. The preponderance (or greater weight) of the evidence must support the establishment of North Carolina domicile twelve months before the beginning of the academic term (i.e., the first day of classes) for which you request the classification. If the evidence shows a cluster of significant events occurring at about the same time (within the same week, for example), we'll start counting from that point to determine if the twelve-month requirement has been met. If instead the evidence has gradually accumulated over time, we must decide at what point a preponderance of the evidence shows intent to establish North Carolina domicile, and that is the date on which the twelve-month period will begin. If this date is after the first day of classes for the term specified on the application, we'll be unable to render an in-state decision for the term in question.
