I can tell you from the california board's perspective. You absolutely CAN become an RN but with 3 dui's you will be considered a substance abuser. What they will want to see is that you are sober, have gone through some sort of recovery program such as day treatment, residential, or intensive outpatient program, are attending 12 step meetings (get card and have signed each meeting for proof), have a sponsor, possibly doing volunteer work, letters of recommendation, and if possible have documented sobriety (there are different ways to do this such as signing yourself up for testing, a program called sober link, or through you medical insurance chemical dependency program). I have 2 dui's and a misdemeanor reckless driving with injury. I got my lvn license from a private vocational school and my rn license from a public community college. At no time was my background an issue with either school just the nursing board. When you are issued an RN license from the board it will almost certainly be a probationary license. This will include nurse support meetings, 12 step meetings, and biological fluid testing ranging from 3-5 years. All of this was worth it to me because sobriety has changed my life and being a nurse is my calling and I would do anything and jump through any hoops to be a nurse. All these steps feel minor compared to how complicated my life was when I was using. If you don't become sober and make excuses for why the dui's happened I can tell you all bets are off with the board and your chances to get your license will be zero.
