Our Malaysian passport is able to take us to 163 countries without the need for a visa. Quite an accomplishment, putting us into 9th place based on The Henley & Partners Visa Restrictions Index. You need to register (for free) to download the index (but you can also download it here [pdf format] since they have a poor of enforcing the registration process). Or if you are lazy, just refer to images below 🙂
We are tied with Malta for 9th place. Out of the 28 countries occupying top ten places, 20 are in Europe, and 6 in Asia+Australia+NZ. The remaining two are US and Canada. The worst 4 countries are Afghanistan, Iraq, Somalia, and Pakistan which are accepted in between 28 and 36 countries only.
small caveat, this is based on data up to 2013 July 1st regulations.
It will be interesting to see an index of countries allowing visitors without visa. Wonder where we will stand.
