Having a powerful passport doesn't help in waiving off visa restrictions but for sure helps in easing them up. A passport ensures free movement of a person from one country to another. For example a student from Ghana can travel to only 82 countries in the world without prior visa approval which is totally opposite for a Dutch student. Students with rather less powerful passports might have to go through more intensive checkings and expensive visa approvals than students with more powerful passports. Here is a list of the most powerful passports in the world-
Japan (193 destinations)
Singapore and South Korea (192 destinations)
Germany and Spain (190 destinations)
Finland, Italy and Luxembourg (189 destinations)
Austria, Denmark, Netherlands and Sweden (188 destinations)
France, Ireland, Portugal and UK (187 destinations)
Belgium, New Zealand, Norway, Switzerland and United States (186 destinations)
Australia, Canada, Czech Republic, Greece and Malta (185 destinations)
