My study permit was approved on 6 July and I received OPR, processed by London office, UK.
I submitted on 28 April 2022, became reviewing on 6 July and received the OPR on the same day.
I sent my passport on 6 July and today is 12 July and I still have not received my returned passport.
As it will still take a few days for the passport to be mailed to me, ircc office not working on weekends, so it is impossible for me to receive the passport with the visa attached by 17 July at the earliest. One of my friends has been waiting for over 2 weeks and still has not received her passport back.
If you have an urgent need to travel or need to order a air ticket, even if you have been issued with an OPR, please leave enough time early to wait for your passport to be sent back.
