It thought that you have to graduate from a high school in Georgia and had to attend school for at least 1 year (all of her senior year) at a minimum. I'm not real sure.
ETA:
Here is what I have found:
To qualify for in-state tuition:
403.02 CLASSIFICATION OF STUDENTS FOR TUITION PURPOSES
(1) If a person is 18 years of age or older, he or she may register as an in-state student only upon showing that he or she has been a legal resident of Georgia for a period of at least 12 months immediately preceding the date of registration.
Exceptions:
A student whose parent, spouse, or court-appointed guardian is a legal resident of the State of Georgia may register as a resident providing the parent, spouse, or guardian can provide proof of legal residency in the State of Georgia for
at least 12 consecutive months immediately preceding the date of registration.
A student who previously held residency status in the State of Georgia but moved from the state then returned to the state in 12 or fewer months.
Students who are transferred to Georgia by an employer are not subject to the durational residency requirement.
(2)
No emancipated minor or other person 18 years of age or older shall be deemed to have gained or acquired in-state status for tuition purposes while attending any educational institution in this state, in the absence of a clear demonstration that he or she has in fact established legal residence in this state.
If a parent or legal guardian of a student changes his or her legal residence to another state following a period of legal residence in Georgia, the student may retain his or her classification as an in-state student as long as he or she remains continuously enrolled in the University System of Georgia, regardless of the status of his or her parent or legal guardian.
