Desree. If this is the copy that was issued to you from a goverment office such as the city, county, or state it is fine. If it is a copy of that instrument or issued by anyone other than the government of the City, County, or State then it is not good. Some have raised seals, (mine does and is a 8x11 piece of paper issued by the town in which I was born), and some do not have raised seals, (my wife and kids have a wallet sized card issued in the county for the state that does not have a raised seal). Best bet is if you have the time get a passport. You need the same document to include with your application then as well.
