Who May Submit a Case Problem to CIS Ombudsman?
If you are experiencing problems during the adjudication of an immigration benefit with U.S. Citizenship and Immigration Services (USCIS), you can submit a case problem to the CIS Ombudsman using DHS Form 7001 (CIS Ombudsman Case Problem Submission Form). To submit a case problem on behalf of somebody other than yourself, who experiences a case problem with USCIS you should ensure that the person the case problem is about (the applicant for a USCIS immigration benefit, or the petitioner who seeks to obtain an immigration benefit for a third party) consents to your inquiry (see Submitting a Case Problem using DHS Form 7001: Section 15 Consent)
