While this would just be considered a first lifetime DUI, the prosecutor may still consider your prior arrest for DUI when making a plea recommendation. As a former prosecutor in Fulton county, I am very familiar with the types of offers the prosecutors in Atlanta and Fulton may make and would be happy to speak to you about how I can help you with your new case. Feel free to call me at 678-522-9540 if you would like to discuss further.
Yes, it is possible. More importantly, based on the facts of the case, you would want your lawyer to look into potentially having the case reduced or amended to a charge that carries no license suspension.
Yes. It is possible for your probations to run concurrent, or at the same time as one another. However, you can only use your first offender once. You may be pleaing guilty under a different statute like conditional discharge assuming it is a drug or alcohol related charge, but otherwise you may want to consult with an attorney to help you with this matter. Let me know if I can help.
Assuming there are no limitations with your bond (and there shouldnt be), you can certainly leave the state so long as you come back or have an attorney appear on your behalf for any scheduled court appearances.
