A. Yes, you may be eligible to file an appeal or a motion on an unfavorable decision.
An appeal is a request to a different authority to review an unfavorable decision. You may appeal certain USCIS decisions to the USCIS Administrative Appeals Office (AAO) or the Board of Immigration Appeals (BIA), an office within the Department of Justice. The BIA and the AAO are administrative appellate entities that have jurisdiction over different types of immigration cases. Your denial or revocation notice will provide information about whether the decision may be appealed and where to file your appeal.
A motion is a request to the USCIS office that issued the unfavorable decision to review its decision. With certain exceptions, you may file a motion to reopen or a motion to reconsider if you received an unfavorable decision in your case. You may file a motion even if your case is not eligible for an appeal.
