I am a PR and was in a Dui situation last year. My trial finished a few weeks ago and I was acquitted. You will not be able to apply for PR until your case is closed and if convicted, it will almost be impossible to get PR at least for 5 years. Getting convicted can have a major impact on jobs and travel as well. All I have learnt from this is to never ever drink or drive. It can destroy your and other's lives.
My limits were low right around 0.09 and that helped. Secondly what helped was getting a good lawyer. Do your research, not what just google recommends or the so called DUI specialists. Get an experienced and reputable Criminal lawyer. I know that it can be very expensive to get a good lawyer, but a conviction can have a huge impact on your life.
