What is the submission information in the letter?
if it's a permanent residence application, I think you can, but it'll be easier to send it through VFS, cos they'll provide tracking information every step of the way. if you're in Ghana, just send a mail to
info.canghaiom@vfshelpline.com and request for the necessary information for submitting your passport. but if you're in Nigeria, send an email to
info.cannig@vfshelpline.com.
if you're in Nigeria you can also send straight to VFS Accra, just send a mail to the Accra address and state that you want to send your passport to them from Nigeria
Sending straight to VFS Accra is faster but more expensive compared to sending through VFS Lagos. it'll take Accra about 2 weeks to send your passport back but people that have sent through VFS Lagos have said it takes about 6 weeks.
I personally sent straight to Accra VFS cos I didn't want to wait 6 weeks and I got my passport back in exactly 2 weeks.
But if its a Visiting Visa, I can't tell because I have no information on that. because I've seen people that send their passports to Nairobi from Nigeria for Temporary Visas.
But if you're Ghana and it's a visiting visa, just contact VFS and let them know.
Goodluck
