I have multiple violations and just finished a 3 year probation for petty larceny. My green card has expired in 2015, how should I proceed ?

As you have eight altercations with the law under which you received violations and the last time a misdemeanor, I suggest that you bring copies of all the dispositions of your arrests to an immigration lawyer who can evaluate if there are risks to your renewing your green card.
