I am a citizen of india living in the United states on a H-1 visa.  I
recently had a DWI conviction in the state of North Carolina.  I
realize I made a mistake and regret it.  However, will this impact my
getting a green card.  My company has not applied for my green card
yet but will do so soon.  I have no prior problems with the law.  My
conviction is the lightest one (license suspended for 1 year with
limited privileges to drive to and from work and for education and
household requirements) and I have been told that since this is my
only offense, I shouldnt have a problem with the green card process. 
I would appreciate an answer from either someone who has been in a
similar situation or an immigration attorney who can guide me with
this.
Thank You
