The Nigeria Immigration Service (NIS) has started a system upgrade and maintenance on its passport portal.

This was made known in a statement signed by the Service Public Relations Officer, Deputy Controller of Immigration (DCI) KT Udo.

According to the NIS, there will be a temporary disruption due to the upgrade in its passport application portal for applicants within Nigeria.

The upgrade will however not affect passport applications for Nigerians living outside the country, ensuring continuity of service for applicants abroad.

The service stated that its team is “working tirelessly” to complete the upgrade and restore full functionality within 72 hours.

The statement reads: "The Nigeria Immigration Service wishes to inform the public of the following:. We are currently conducting a system upgrade and maintenance on the passport portal for applicants within Nigeria.

"Please note that this upgrade does not affect other services, including passport applications for those applying from outside Nigeria, which remain fully operational. "Our dedicated team is working tirelessly to complete the upgrade and restore full service within the next 72 hours.

"We sincerely apologise for any inconvenience this may cause and deeply appreciate your patience and understanding during this period.

"The Nigeria Immigration Service remains committed to serving you efficiently and with excellence."
