For now and until the election is over, keep as much money out of the country as you can. Set up a dollar account with your UK bank (watch the interest rate!) if you want and arbitrage between Pounds and Dollars. It might be a good time to by dollars now and wait for them to come up during the year.
Use the ATM machines for daily living.
Use a credit card if they accept it for larger purchases and international money transfers from your overseas bank for major stuff, like a house. For major stuff like repairs, kitchens, furniture etc pay as little as you can up front. For services pay nothing up front if you can get away with it.
Get a good attorney to advise you on larger purchases and don't let on you have some money or they'll skin you :classic:
Best of luck in the DR!
