HI Madam, here is what i did, when I got my passport request and re-medical through mail in Kabul, I had to first do my re-medical here in Kabul and the doctor sent it via DHL courier to New Delhi office, then I had to take my passport and photocopy of my re-medical form signed by the doctor to Islamabad and sent it to CHC-I through TCS courier, your husband can't and send the passport from Afghanistan to Pakistan and CHC-I does not accept it, there other thing to keep in mind is that your husband needs to give CHC-I an address inside Pakistan so that they can send the passport with visa to that address inside Pakistan, hope your husband gets his PPR soon and eventually his visa, please do pray for me and everyone else waiting for their cases to be finalized,
