I send money back home every month. For every $1000 USD, you pay $25 on Western Union. You can send the money to a bank account, if you want, or cash-at-the-window (or cash on delivery, in some countries).
I’ve been doing this for the last 4 years. Zero hassle.
To exchange/transfer more than 500 USD in a Bank you need a bunch of papers, just as someone said above, but for WU, all you need is to bring your own USD.
