We came across this great infographic, which shows you which countries have the most powerful passports in terms of which other countries you can go to without having to get special visas, write lengthy begging letters to the government, sneak in in someone's hand luggage, etc.
At the front of the VIP section and being waved in under the velvet rope of immigration are Finland, Sweden and the UK. Their perennial plus-ones include Denmark, Germany, Luxembourg (sneaky little devils) and of course, everyone's entitled young cousin, the USA. Over 170 countries welcome all these nations with open arms.
Looking rather like their dance card is empty are the countries that virtually no-one will let in without a severe pat-down and police background check are places such as Pakistan and Somalia (32 countries), Iraq (31) and poor old Afghanistan, which has visa issues with all but 28 friends on this planet.
Of the big economies, it's surprising that China is so far down the list - just 43 countries lay out the welcome mat for them, though given the stories we've heard about trying to get visas to get INTO China, they might want to show a little willing to get invited to the cool kids' parties.
