Do you also have friends who have successfully sent their passports outside Africa? We have to be careful, some people post opinions to look like facts. The reason our applications are spread around different visa offices is load sharing. No one wants any visa office overwhelmed with work. Just saying. I do not know this for a factI strongly disagree... You can send your passport to any VO. and take note: the reason why you are advised to avoid ACCRA or VFS Lagos is because they take far too long time to process. just like they take time to process PPR.
I have friends who have sent passport to Accra since 22nd October. They are still waiting for their passports.
