The immigration consequences of convictions depend on the exact language of the statute under which the conviction took place.
You need to retain an experienced immigration lawyer to review all the facts, advise you, and handle the case.
1. Obama's action is a policy and not a law. It is not an Act.

On the issue of the juvenile delinquency charge, it sounds like you were given some type of informal probation pursuant to Welfare and Institutions Code section 654 or even a police department diversion program where you participate in some classes or community service without a petition being filed in juvenile court. If you have not had any problems since the incident when you were 15 years old, you may be able to petition to have your juvenile record sealed and destroyed. You should contact an experienced juvenile delinquency attorney in your area to see if you are eligible to do so. As to the immigration issues, I leave that to the immigration lawyers. Good Luck!
