If your Petition for Alien Worker is denied, the denial letter will tell you how to appeal. Generally, you may file a Notice of Appeal along with the required fee at the appropriate USCIS Regional Service Center within 33 days of receiving the denial. Once the fee is collected and the form is processed at the Service Center, the appeal will be referred to the Administrative Appeals Unit in Washington, D.C. Sending the appeal and fee directly to the AAU will delay the process.
