There is no typical timeline for either of these court appearances. You should ask your attorney these questions, and if you have not hired an attorney, you really should consider doing so. Sometimes the criminal court date arrives before the ALS hearing; most of the time, the ALS hearing occurs first. There's too much at stake for most of my clients to handle a DUI without an attorney.
When you hire an attorney, you authorize the attorney to attend court for you, that is, to go to court instead of you for as long as it takes before trial or the plea date. The attorney's job is to attend court so you can do your job away from court. The attorney's job is to negotiate the case when the prosecutor blesses him or her with time. If you're not sure your attorney is doing things correctly, that's a sign that you are not comfortable with your attorney and it may be time to replace...
If you are serious about getting a plea deal for a reduced charge, you need an attorney. While it's not unheard of, it is extremely rare that a prosecutor who is truly interested in justice above getting a conviction (as they are all sworn to be) will just agree that you are a nice enough person worthy of avoiding a DUI conviction. These are great questions to take to an experienced DUI defense attorney.
You really need an experienced DUI defense attorney. I can't tell from your question what kind of school you're starting, but I'm not aware of too many professions, other than driving, that will automatically disqualify you from the program. If you insist on handling this yourself, be careful what you tell the prosecutor, because the solicitor can use that information against you in an effort to win the case.
This is NOT the time to be cheap. A DUI is a felony or misdemeanor criminal offense, not just a traffic ticket. If you are convicted of a DUI, there are mandatory penalties.
You need an experienced DUI lawyer whom you feel confident will get you the best results possible. It doesn't sound like you feel this way about your current lawyer. Talk to your current lawyer, bring up these issues. If you still don't like his answers or advice, please interview several others until you find one you...
This is a great question to ask your attorney. If your license is suspended at the ALS hearing, your attorney should advise you what steps to take next. Otherwise, contact DDS to make sure that the information you need is accurate. After all, the DDS is in charge of your license. Don't rely on family or friends who may not know the real answer.
While I agree with Evan Watson, it also depends on any license suspension you may have had in the past. You should contact the Department of Driver Services to clarify what effect an administrative license suspension will have in your case.
Unless any of these charges were dismissed without prosecution, you can't have these expunged from your record. If the charges were amended to a different charge (such as driving without your license in your possession, or Reckless Driving), the original offense will still show up on your record. The Georgia legislature has a new proposed law to change expungements. You should write to your Georgia representatives (state government) and ask them to vote in favor of expunging more charges.
