Pls, guys is it possible to be posted to where i got a request letter from which is not registered under NYSC.
Thanks.

If you just redeploy to the state and has not done documentation. Carry the letter to NYSC secretariat. Then write letter of posting and attach the letter you have with you to it. In a matter of days, the ppa will reflect on your portal.
But if you didn't redeploy, you will need a letter of rejection from where you were earlier posted. Then go to nysc zonal office then write letter of reposting specifying the place you want them to post you. Attach the request letter to it.
There is nothing like a PPA is not registered with NYSC.
Good luck. I hope you are not in SS state where they will never grant your request but will want to use you as a teacher with no payment

Thanks so much bro, I really appreciate, I have request letter, reposting letter and rejection letter that was given to me from the previous place i was posted to but he kept on saying the place is not on the system which i don't understand.
