Nyer,
My (Dominican) wife and I keep only what we could afford to lose, here, in the D.R. Don't expect anything bad happening, but it's very easy to open up internet accesible accounts with credit cards and paper checks in U.S. dollars in the U.S. or other countries, even if you're not a U.S. resident. They're not easy to find. It just takes time to find the right companies/banks, but when you do you'll wonder why you kept anything here.
We finally got everything set up properly last month and it's like freedom has finally arrived! No more wire transfers, bugging the local banks, worrying about echange rates.
Ah! The tranquility! back to the beach!
Tom
