The majority of people will probably be able to tell you what Prince George weighs, his height, the colour of his eyes and his middle names...but the little royal still needs to carry a passport, just like the rest of us.For his trip to Australia when he was just nine weeks, he needed to get a baby passport (and the royals had to pay...$65 if you're interested, though this peeves me off somewhat. I paid more for mine!) and along with his parents, he needed to adhere to customs and immigration rules. Though it's customary for this process to be fast-tracked.
