The petition for review must be brought against USCIS, and service of the petition for review must be made upon DHS and upon the USCIS office where the hearing was held pursuant to 8 CFR 336.2 .(c)Standard of review. The review will be de novo, and the court will make its own findings of fact and conclusions of law. The court may also conduct, at the request of the petitioner, a hearing de novo on the application for naturalization.(d)Exhaustion of remedies.
