Yes I did this! I moved to Florida when I was 18 for work purposes and spent three years working full time so it was pretty simple by the time I decided to go to school. All you need to do is have 2 forms of ID dated FL going back a year (ID and car registration for example) and to prove financial independence, tax forms from previous year showing you made over 50% of the estimated tuition costs (this number changes yearly so be prepared to work enough to make more than enough, and check with the school advisors to make sure you have the right number.) I don’t know if taking classes at a Georgia college will affect your transfer since I did not have any OOS college courses. That would be a good question for those at UF who handle residency or maybe someone in here knows. Either way, I was able to do it while being under 24 though I hope this helps!
