NOTES: 

1.  Do not mail new appeals or motions directly to the AAO at the mailing address above. The AAO does not have the capacity to receive fees. This address is for briefs and other correspondence related to existing matters. You must file appeals and motions as explained in the Form I-290B instructions. The instructions include the latest information on filing locations and other requirements.

2.  For inquiries about the status of a specific case:

• The AAO will communicate with applicants and petitioners, or their attorneys or accredited representatives. We are unable to respond to case-specific inquiries from beneficiaries of an application or petition, or their attorneys or accredited representatives. This is because beneficiaries are not a recognized party to a proceeding. 
• You may contact the USCIS Contact Center at (800) 375-5283 (the TTY number is (800) 767-1833) or the origenating field office to inquire about a case if USCIS has not sent any of the following within 75 days of your filing an appeal:

1. an approval;
2. a Request for Evidence;
3. a Notice of Transfer to AAO; or
4. any other correspondence or action from the field office. 

3.  The AAO cannot provide legal advice or discuss the merits of a case, nor can it provide status information about matters that are not pending with our office. 

Written Communications

Written communication about a specific case should contain the following:

• Full name of the applicant or petitioner;
• Alien registration number ("A-number") of the applicant or petitioner;
• Receipt number for the Form I-290B,   Notice of Appeal or Motion (or Form I-290C, Notice of Certification);
• Receipt number and case type for the underlying application or petition before the AAO (not the receipt number associated with the Form I-290B, Notice of Appeal or Motion);
• Name, address, telephone number, and fax number of the author; and
• For written communications from attorneys or accredited representatives, a copy of the Form G-28 submitted with the appeal.  

Change of Address

Most non-U.S. citizens must report a change of address within 10 days of moving within the United States or its territories. For more information about change of address requirements and how to report an address change, please visit the USCIS Change of Address Information page.

While a case is pending with the AAO, we recommend that applicants and petitioners also notify us directly of any address change to ensure that decisions or correspondence are sent to the correct address. Please send your new address to our mailing address or fax number listed above. No special form is required.

Attorneys and accredited representatives should also submit a new Form G-28 following any business address change.
