Pls I need help here, I submitted my application July 2020, and I was asked for Additional Document which was submitted October 2020, I did get to here anything again but when I mailed them sometimes in 2021 I was told my case was referred to PIU, I don't even know what it meant then, but June 2022, I received an official mail also stating my Applications has be referred to PIU, that they are unable to disclose the reason for now. Til today I haven't heard from them. Pls what can possibly be wrong
