Yes, this very much may cause problems for you. It's unlikely that you'll be eligible for citizenship with your record - you get one, and only one, petty theft exception. Anything else is looked upon unfavorably.

Since you already have an immigration attorney, you really should be addressing all of your concerns to him/her, as s/he has access to all the details of your case.
