Alhamdulillah I have received the following from LVO today:
Please be advised that this file has reached the final stage of processing is now ready for visa issuance. Since you appear to be resident in Pakistan, and Pakistani law does not permit the mailing of Pakistani passports from Pakistan to other countries, we will not ask you to submit your passport to our office in London. Please refer to the attached document for full instructions regarding submitting your passport(s) to the Islamabad visa office within the next 30 days so that your permanent resident visa(s) can be issued.
Very happy and pray for everyone to be united with their spouses very soon InshaAllah...
