Thanks Betty! Would love a second opinion... this is what I got from someone I have not yet officially retained their services. I emailed them my expunged court documents:
If this is your only conviction, then you be fine traveling in and out of the US. You should bring this document with you. The DHS will likely put you through second secondary inspection because of it so that they can ask you questions. It is a conviction for reckless driving. Ultimately, they will let you reenter the US.
Since the conviction took place on 10/29/08, you actually want to wait at this point until 10/30/13 to submit your citizenship application. We can assist you with the application should be interested. Please contact my office below for a consultation at that time.
