How Immigration Security Checks Work

To ensure that immigration benefits are given only to eligible applicants, USCIS adopted background security check procedures that address a wide range of possible risk factors. Different kinds of applications undergo different levels of scrutiny. USCIS normally uses the following three background check mechanisms but maintains the authority to conduct other background investigations as necessary:

• The Interagency Border Inspection System (IBIS) Name Check— IBIS is a multi-agency effort with a central system that combines information from multiple agencies, databases and system interfaces to compile data relating to national security risks, public safety issues and other law enforcement concerns. USCIS can quickly check information from these multiple government agencies to determine if the information in the system affects the adjudication of the case. Results of an IBIS check are usually available immediately. In some cases, information found during an IBIS check will require further investigation. The IBIS check is not deemed completed until all eligibility issues arising from the initial system response are resolved.

• FBI Fingerprint Check—FBI fingerprint checks are conducted for many applications. The FBI fingerprint check provides information relating to criminal background within the United States. Generally, the FBI forwards responses to USCIS within 24-48 hours. If there is a record match, the FBI forwards an electronic copy of the criminal history (RAP sheet) to USCIS. At that point, a USCIS adjudicator reviews the information to determine what effect it may have on eligibility for the benefit. Although the vast majority of inquiries yield no record or match, about 10 percent do uncover criminal history (including immigration violations). In cases involving arrests or charges without disposition, USCIS requires the applicant to provide court certified evidence of the disposition. Customers with prior arrests should provide complete information and certified disposition records at the time of filing to avoid adjudication delays or denial resulting from misrepresentation about criminal history. Even expunged or vacated convictions must be reported for immigration purposes.

• FBI Name Checks—FBI name checks are also required for many applications. The FBI name check is totally different from the FBI fingerprint check. The records maintained in the FBI name check process consist of administrative, applicant, criminal, personnel and other files compiled by law enforcement. Initial responses to this check generally take about two weeks. In about 80 percent of the cases, no match is found. Of the remaining 20 percent, most are resolved within six months. Less than one percent of cases subject to an FBI name check remain pending longer than six months. Some of these cases involve complex, highly sensitive information and cannot be resolved quickly. Even after FBI has provided an initial response to USCIS concerning a match, the name check is not complete until full information is obtained and eligibility issues arising from it are resolved.
