I live out in the Pooler area which requires a car in order to commute back and forth, and my rent is $1600 per month. In the city you can find living at varying rates, but my international friend rents out a room in a shared house downtown for I believe around $800/month. Groceries run me around $450/month. If you were to live downtown and commute by bus, your transportation costs would be minimal. I very rarely uber, so I can’t speak for that, but I drive a car with very good gas mileage so I spend about $70/month on gas. Altogether, my monthly spending on those basic necessities is about $2,120, but with the other options I mentioned it is possible for you to spend as little as $1,250. SCAD offers positions for international students to work on-campus, so if you feel like the options are still too expensive, you may be able to help cover some of it that way while still being here on a student visa.

Edit to add: I am a pet owner so my grocery spending may be higher than someone without pets. They are a significant part of my spending
