The results of international surveys typically aren't usually terribly plausible, but a World Values Survey on immigration ideologies in 48 countries seems likely.
A glance at the table shows there’s a moderately high correlation between holding theoretical open borders views and living in the kind of country that nobody in their right minds wants to immigrate into.
Here’s your top ten most pro-Open Borders countries: Vietnam, Burkina Faso, Rwanda, Ethiopia, Mali, Morocco, Romania, Uruguay, Peru, and India.
Yup, those are some real high desirability destinations.
(In case you are wondering, Israel, whose government uses the term "illegal infiltrator" to describe "undocumented workers," was apparently not surveyed.)
In contrast, the ten most anti-open borders countries are ones that have a lot to lose and are in more danger of losing it.
South Korea, Taiwan, and Japan are rich, competent, nationalist NE Asian countries. Norway and Australia are rich whitopias. Trinidad is the richest country in its region due to oil, and it already has a lot of ethnic tensions that don't need augmenting. Thailand and Malaysia are among the richer countries in their regions, with poor, heavily populated neighbors such as Burma, Indonesia, and Vietnam.
Egypt and Jordan are interesting. I suspect their attitudes are similar to Israel’s, and for the same reasons.
1) None of those three countries wants the Palestinians of the West Bank and Gaza. They all remember what happened when Jordan kicked out the Palestinians in 1970 and they moved to Lebanon: that upset Lebanon’s delicate balance of power and 15 years of civil war ensued.
2) Egypt, Jordan, and Israel are all on the land route from sub-Saharan Africa to the rich North. They would all be overrun with sub-Saharans. Middle Easterners notice how Col. Qaddafi’s policy of inviting in large numbers of sub-Saharans did not improve his popularity with native Libyans.
