Acting President Yemi Osinbajo has directed the extension of the 2017 N-Power application by two weeks.
The application portal will now close on July 27.
In a statement on Sunday, Afolabi Imoukhuede, special assistant to the president on job creation, said the selection process for the second batch would be characterised by transparency.
He said about 2.45 million graduates have applied for the second batch of the national social investment programmes (NSIP), which is meant to take 300,000.
The first batch engaged 200,000 young Nigerians in the N-Power volunteer corps programme. They were deployed to public primary schools, primary healthcare centres and agriculture development project centres.
The portal for N-Power to engage additional 300,000 into the 2017/2018 phase was reopened on June 13.
