The CSIS just does your security clearance but the background check is done by the CIC visa posts of the country you have lived in. So if you live in USA but you have had your education in India they will call them or email them to check if what you claim is true. CSIC just does your name check against all the violent groups through most of the data base. I read in another forum that they prefer immigrants from USA because they have access to all the USA criminal records, and if USA allowed them in so they must be clean and they also do a clearance from FBI. Most of the problems are because of CSIC as they are backlogged to get clearance.
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. If there is a record match, the FBI forwards an electronic copy of the criminal history (RAP sheet) to USCIS. Although the vast majority of inquiries yield no record or match, about 10 percent do uncover criminal history (including immigration violations). 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 and
visa background search.
