Visa Restrictions Index, 2011
There is a wide variety of regulatory regimes controlling the movement of foreign nationals. One such restriction concerns the emission of a visa granting temporary access to a visitor as long as the purpose of travel is leisure or business. While the nationals of developed countries tend to have few traveling restrictions, those of developing countries tend to have limitations with less countries open to travel without a visa. A national of Denmark can travel to 173 countries or territories without a visa while a Chinese national can only travel to 40 countries without a visa. The rule of the thumb is that developed countries impose travel restrictions on nationals of countries that have a high likelihood of using the pretense of tourism or business travel to emigrate. As economic development takes place, travel restrictions tend to become less stringent.
