I have a query. I got my ITA in May and I am in the process of collecting documents. My passport expiry was in 2021, but it did not have my spouse details and my updated address. During the PCC process, the police officer at PSK advised me to get my existing passport updated. I have my PCC now, but I will get my new passport in a weeks time. I am just a bit worried that because the new passport will have a different number from what I have in my PCC, my application could be rejected. I am thinking that I will add a letter of explanation along with my submissions explaining this. Has anyone else faced this? Please let me know.
