Please go to this link: http://www.uscis.gov/humanitarian/co...s-daca#request DACA

Then scroll down to "National Security and Public Safety Guidelines"

Read that section and see which type of misdmeanor you fall under... if it's a non-significant misdemeanor, you have a good chance of getting approved. Some people are taking 1 year to get approved, so you with a record before, it's not surprise they taking longer than you might think they should take.
