Depending on the size of the loan, family can be quite helpful too. My wife is paying money (in pounds) into a UK bank account for her father, and he is paying the equivalent (in dollars at whatever the current exchange rate is) into her student loan. This will only work in the short term (her family are going to visit, not emigrate!) but it gives us time to save the money up to pay off big chunks of the loan at once (from memory, last time we sent a chunk over the bank charge was fixed at about 30 quid - so for big sums the cheapest way to send money).
