The BSIS estimates about 10 days, if you use the online application. Using the mail in application can take up to 4 weeks. Of course, the time depends on how long your criminal background check takes and how many applications the BSIS is processing. The BSIS handles a large number of security guard, proprietary security guards, proprietary private security employer, private patrol operator, firearm, training provider, alarm installer, repossession agency, locksmith and private investigator license applications every year, so it takes time for your application to be approved. The DOJ is also processing fingerprints for many of these licenses as well as for police departments.
