2 passports... two different issuing countries... two different passport numbers..... okay same name and DOB.... and same person. The immigration system here doesn't look at faces...finger prints yes... but connecting them within the system here is highly unlikely.
yes that can work. Done it myself last passport renewal. However ...not always without a conversation... explaining both common sense and the finer points of reality.
just as i thought. Been that way for a while now. Not sure if it will change for quite some time. But I have reports of some getting through. As with other things always just depends. Up north is reported being easier for quick bounce as there is far more pedestrian traffic of all nationalities. Remember the number of bounces you already have ...if any... may also be a factor.
