When a case is being actively reviewed by USCIS, it means that the agency is currently processing the case and is in the process of determining if the applicant meets the eligibility criteria for the immigration benefit they are seeking. The USCIS will review all the relevant documents and information provided by the applicant and may request additional information or evidence if necessary. The length of time it takes for USCIS to process a case varies depending on the type of application and the individual circumstances of the case. Applicants can check the status of their case by using the USCIS online case status tool or by contacting USCIS directly.
