Thank you for your reply.
I submitted my documents to the NVC on November 15, 2021; one was rejected; and I re-submitted on April 7, 2022. waiting.
Since I am aware of the backlog in Nigeria, I decided to pursue a master's degree in the UK pending the time the application will be processed and the NVC/ embassy will schedule an interview.
I do not wish to delay my case as I plan to continue with the NVC process concurrently, It would help if I am documentarily qualified and will be able to transfer the case to the UK as Nigeria is behind with backlogs.
