 DHS's time to hire can be pretty lengthy. It's largely due to the vetting requirements and other security clearance processes that they have to conduct. It does depend on what the job is, but that can include everything from a polygraph test and fingerprinting or even a medical exam. In total, DHS's time to hire ranges very broadly. It can go anywhere from a couple of months, in some cases up to a year or even longer, according to the Government Accountability Office.
