Interior CS Kithure Kindiki on Monday made an impromptu visit to Nyayo House to assess the progress.
The CS said the ongoing Rapid Results Initiative (RRI) on delivery of uncollected passports and clearing of the historical backlog is yielding the desired results.
He said the ministry will maintain the momentum on operational reforms at the Immigration Department.
The CS added that he will ensure optimal results are achieved in the application, processing, and collection of passports and other citizenship documents.
"Made an impromptu visit to the Immigration Department's Nyayo House Headquarters to check on the progress and sustainability of the ongoing reforms, engaged citizens seeking services, and assured them of the Government's unrelenting efforts to streamline operations at the State Department for Immigration and Citizen Services," he said.
The CS stepped up efforts to eradicate corruption at the Immigration Department following public outcry over delayed processing of the travel documents.
The uproar prompted Parliament to summon him for an explanation where he admitted that corruption was endemic at the Immigration Department but vowed to crash the cartels.
The CS banned boda boda riders and idlers around immigration offices and declared the area a corruption-free zone.
Initially, there was a backlog of 87,454 passports that were yet to be collected from the Directorate of Immigration headquarters and regional offices.
As a result, Kindiki launched a 30-day Rapid Results Initiative on September 25, 2023, that would see the ministry clearing the backlog.
