They sent mine with certified Xpresspost. I wasn't home so they left a notice and i had to show ID and sign to receive it at the post office. It is kept at the post office for 15 days then sent back to sender.After submitting my application, I was told that the passport will be mailed to me. I can't remember what would happen if the delivery came but I were not home. I remember they briefly mentioned it, but I can't remember what exact consequence is. Do I need to pick it up at a post office, or do I need to call them or something? Can someone explain?
