1st passport timeline
I want to share my experience getting my fisrt passport after naturalisation. It went relatively smoothly, except for a glitch: I already have two citizenships (british is my third); as documents, they asked for the passport that I used to enter the UK (that of one of my citizenship countries), which I provided. They came back to me asking for the ID card (or copy thereof) of my other citizenship country, which I then had to send and caused delays.
I received the passport one day after it being printed. I am still expecting the return of my application documents.
Besides that, all good, although it is a bit stressful to have no passport, no naturalisation certificate, etc. for a bit, and one has to pray that nothing serious happens in the family back home, since any sort of travel is out of question.
