Nigerian Immigration: has anyone (foreigner) been asked to appear before the NIS with relevant papers such as:

evidence of quota (original), PUR (original), CERPAC (original), passport (original), college certificate (original), Cert of Incorp, Mem & Art of Assocn, CO2, CO7 etc? (all in original)?
If so pls advise me how to go about this as I hve received a similar thing in the past one week. Cheers.
