If you are a USC and your wife entered legally, you can file for a green card for her in the US. However if she used a fake or false passport to enter, regardless of age, then under case law, DHS is not considering this a lawful entry in most jurisdictions. This will be a very tricky analysis. You must have a full consult with a competent immigration attorney to carefully review the facts of your wife's case to see if she is barred or eligible.
