I understand that if a person travels internationally for a while, in due course of time, the passport would be filled. In which case he would need to apply to the passport office to get a second and so on and so forth. What is written on the second passport (or whatever number the passport it is.)
The easiest similie to give in this place would be say like a bank passbook, where once its filled, on the second pass-book it will just carry forward your last credit/debit balance and start from there. Does anybody how it works with passports ?
