Can I see your passport , please ?   Is this line for non-residents ?   Yes it is . Residents can queen up in the lines to my right .   Ok . Here's my passport .   What's the expiration date on your passport ?   I think it's soon , maybe in a few months . It was renewed in Beijing , so the new expiry date is on the last page .   I see . Yes , you'll need to renew your passport in a few months . Make sure you don't let it expire while you are in the UK .   I won't .   Do you have anything to declare ?
