In spite of your admissions of your harmful drinking pattern on a public forum such as avvo.com you still have a shot at beating the case at trial if not negotiating a favorable settlement to a lesser...
Even if the court were to somehow defy decades of DUI practice and accept it, your daughter would unfortunately still have issues with DMV unless and until the program is completed.

Absolutely. Hire yourself the best, locally experienced criminal defense attorney you can afford.
Don't get too caught up on Avvo ratings and years in experience as others have suggested. Rather, focus on the experience as it relates to the number of cases handled and overall client reviews. Many time an "experienced" criminal defense attorney in years in practice is not nearly as skilled as one with less years, but one who has successfully handled more cases in a shorter amount of time....
While I applaud your proactivity here, the best move would be to hire yourself a quality, locally experienced, criminal defense attorney to assist in hopefully avoiding having to do any DUI related classes (i.e. winning the DMV hearing and resolving the case for less than a wet reckless or obtaining not guilty verdicts at trial).
What exactly are you trying to accomplish?
Unless you are willing to go all the way to trial in the unlikely event you are somehow successful in being permitted to withdraw your plea with this much time passing after sentencing, you are wasting your time and money.
Obtaining a dismissal under Penal Code section 1203.4 (commonly, and wrongfully, referred to as California's "expungement" statute) should not have much, if any, an effect on the immigration status issue. Contact an experience immigration attorney for the best advice moving forward.
