I'm holding an emergency passport as I'v lost two passports in the last two months. It only has 7 months expiry and I don't intend to renew it after it expires, as I won't be going overseas in the next 5 years. Can I just leave it be and apply for a new one when I need one? I had asked a staff in the post office and she told me I will have 3 years to think about renewal, but I forgot to ask what if I didn't want to renew it. Will it affect my application in the future if I don't do anything when my current passport expires?
