If you notified USCIS after you naturalized you should be fine (actually USCIS should automatically change from F2A to IR1). As to expediting the process, you can try, but I would not hold my breathe.
Good Luck!
Relevant criteria or circumstances that may be considered in determining whether to grant an expedite request include, but are not limited to, the below:
Severe financial loss to a company or person, provided that the need for urgent action is not the result of the petitioner’s or applicant’s failure to timely file the benefit request or to timely respond to any requests for evidence;
Emergencies or urgent humanitarian situations;
Nonprofit organization (as designated by the Internal Revenue Service (IRS)) whose request is in furtherance of the cultural or social interests of the United States;
Government interests, including cases identified by the government as urgent because they involve the public interest, public safety, national interest, or national security interests; and
Clear USCIS error.
Not every circumstance that fits under the criteria or examples above will result in expedited processing. See more information below on expedite criteria and circumstances. For USCIS’ expedite policy guidance, see Volume 1 of the USCIS Policy Manual.
