I gathered the following info from the web.
IBIS is "Inter-agency Border Inspection System". IBIS includes NAILS but also integrates database lists of known offenders from Customs, the FBI, the Drug Enforcement Administration and the Agriculture Department\'s Animal and Plant Health Inspection Service.
The principal portal to the watch list databases is the National Automated Immigration Lookout System, or NAILS, run by the INS. NAILS contains the immigration agency\'s list of deportees and other undesirables, as well as the State Department\'s classified tip-off list and leads from other agencies.
Per the recent INS directive, applicant name must be checked against the IBIS database for inadmissibility. That is what the local INS offices are trying to do. But, they don\'t have access to the system or they lack proper training to use the system.
I believe, IBIS is the same system that the immigration inspectors use at the Port of Entry (like JFK, Miami, etc).
Hopefully, this answers your question..
Don\'t worry..This too shall pass..We\'ll get beyond this point.
Best of luck..
