The e-CERPAC (Electronic Combined Expatriate Residence Permit and Aliens Card) is an essential immigration document issued by the Nigeria Immigration Service (NIS) to eligible foreign nationals. It serves as both a residence permit and an identification card, granting expatriates the legal right to live, work, study, or invest in Nigeria.

Notably, the newly introduced e-CERPAC eliminates the need for post-arrival regularization, as it is processed and issued before the expatriate enters the country. This innovation streamlines immigration procedures, reduces administrative delays, and enhances compliance by ensuring that expatriates arrive in Nigeria with full legal authorization already in place.
