Being a non Georgia resident facing a DUI charge in Georgia is a terrible situation. If you are visiting Georgia and facing a DUI charge you need a local attorney now. There is no clear answer how your criminal case in Georgia will effect your license status back home. Each case and answer is different. You need a local attorney to consult with you about the Georgia administrative license suspension and what if any impact a Georgia DUI conviction can have on your license.
In addition, many if not all, court appearances your judge will typically allow your attorney to appear on your behalf with prior permission.
