The Comptroller-General of the service, Mr Muhammad Babandede, said the portal became effective from 12 midnight on Tuesday.
Babandede further explained that with the reopening of the portal, a new passport application and payment regime had begun.
He said: “Applications and payments for passport services shall be made through the service website, www.immigration.gov.ng
“A chat room facility to guide applicants through the application and payment process has been provided on the portal.
“Upon successful applications, applicants shall make their online booking interview/enrollment appointment on any day, time and location they consider convenient.
“The new timeline for passport production and issuance after a successful enrollment at the selected issuing centre shall be six weeks for fresh applications and three weeks for re-issue (renewal applications).”
According to him, no applicant who has yet to make online application and payment shall be allowed into any of the issuing centres for passport processing.
The comptroller-general added that pplicants would be contacted through the email addresses and phone numbers they provided during application when their passports were ready.
He, however, cautioned Nigerians to avoid patronising touts as the entire process had been made seamless for effective and efficient service delivery.
Babandede warned passport racketeers to desist from acts capable of undermining the NIS reform efforts to avoid very strict sanctions. (NAN)
