The thing is i mailed the documents and received them back. But then i got a email saying supporting documents havent been received and to send them within 10 working days... i mailed them again yesterday and they have been signed for today.
I would take a screenshot of the tracking that says it has been signed for and print it our for your records, you never know, it may come in handy. All you can now do is sit and wait.
I sent everything off from here, the wife went to her Biometrics in Islamabad, did her Biometrics, submitted the passport and that was that. I did the rest from here. I got the documents back after 2 weeks of the solicitor sending them off accompanied by a letter from Sheffield.
