HI,

I would recommend that you do not smile in your passport photo. In some countries like Australia, they have automated kiosks that take your picture and then compare it to your passport photo. If you're smiling in your passport photo, then you need to smile for the kiosk. Smiling may be difficult after a 15 hour red eye flight.

Please help.


I didn't find the right solution from the Internet.
