Thanks.
Here you go.
The following background checks INS does on Naturalization applicants-
[1] IBIS: This check has validity of 35 days - this check is against IBIS (maintained by USCPC - Customs and Border Patrol) using applicant's full name and date of birth (without place or country of birth). This check is done by USCIS internally through a connection to IBIS. A no hit is termed "IBIS OK" in USCIS' jargon. An "IBIS DNR" (Does Not Relate) is when a match exists but does not relate to the applicant, which is a no hit as well. IBIS is exempt from FOIA requests, that is, a person cannot use FOIA to find out if his/her name is in IBIS.

[2] FBI Fingerprint (FD258) Identification against NCIC database - This has a validity of 18 months. Any applicant can call FBI NCIC (Clarksburg, WV) to find out if his/her fingerprint result has been sent back to USCIS. Work through various voice prompts to talk to a live representative. The results of this check are normally returned within 24 hours for person with no criminal records or outstanding warrants. No hit is termed "NO IDENT" in FBI jargon. An FOIA request (with FD258/fingerprints) would reveal if a record exists or not.
[3] FBI Name Check against Central Records System (CRS) - This check basically searches to see if the applicant has ever been a subject/target of any FBI investigation. There is no documented validity period for this check. This check can take anywhere from 1 day to 1 year. No hit is termed "NO RECORD" in FBI jargon. A FOIA request would reveal if a record exists or not. FBI may not disclose full details but will acknowledge if a record exists. Also, presence of a record does not mean that it is something
negative.
