Prior to adjudication of the waiver, USCIS staff research the Central Index System (CIS) to determine whether an A-file exists for the applicant. If there is a record of an A-number, staff will note the A-number on the Form I-601 and also:

• Review the EOIR screen through RAPS, EARM, or CIS to determine whether the applicant has been previously placed in removal/deportation proceedings before EOIR;

• Review CIS, CLAIMS, the EOIR screen and, where appropriate, RAPS to determine whether the applicant has applied for asylum or adjustment of status and, if so, note the dates the applications were pending;

• Review EARM for any information regarding prior deportations;

• Review CIS for NAILS record(s). If CIS indicates that there is a NAILS record, IBIS must be queried to determine the nature of the NAILS record, even though some of the information may already be contained in results of a CLASS check Events that result in the NAILS hit may have occurred between the IV application/CLASS check and the time the waiver is adjudicated
