In many countries it is compulsory even for foreign workers to pay into a pension fund from their earnings.
Most countries though allow foreign workers to claim a pension refund if they leave the country permanently.
In Germany pension refunds are about €1520 while pension refunds from Japan are about €840.
Australia also allows temporary workers to claim superannuation refunds and these can be worth thousands of dollars.
