@Gbemife . You were right. I called them up again and a female agent answered. She was so sweet. Told me everything about my application. Apparently within 4 months of applying, everything had been completed except for the security screening which has been in progress for 14 months now (her exact words) . She said they'll be sending a reminder to the agency soon. Nothing else to do but wait.
Well, atleast I know something. Better than being in the dark like I was until now.
Thank you for that advice, buddy. I would've never called back so soon if you hadn't told me to. Much love, brother
