If your username is a reflection of your real name, I would urge you to change it. Directions for how to do so can be found here:
Although you’re an international student, it appears as though your entire high school time was at a Georgia high school, so that might help your odds at UGA. I’d say UGA is a toss-up (could go either way and I wouldn’t be surprised), Augusta is highly likely, and you have a low probability of admittance at Georgetown.
How much is your family willing and able to spend on your college, per year? Also, does your family have all that money in the bank already? As an international student, to get a student visa the government will expect to see the funds in place in order to have the visa granted. Or are you considered a permanent US-resident (i.e. green card), in which case the international student part is pretty moot.
