Has anyone worked in a call center here?
I have.
It sucks.
Long hours, **** pay, overseeing bosses who will can you if you aren't giving them the numbers they want.
If you are working illegally say goodbye to your severance pay, you won't see it.
As an American, learn from my experience and save yourself many, many headaches.
Invest in a power inverter, a good one.
Pay a little more for an apartment in a quiet neighborhood.
Have a reliable and decently fast computer/laptop.
Figure out how to get a US phone number (it's not hard and it's free).
Get at least 5mbps internet.
Work online. I recommend oDesk and Elance.
Laugh your way to the bank when you make 3x, 4x, 5x more than anything you could ever make in a call center.
You're going to need 6 months of living expenses for daily activities and enough to cover the above expenses I mentioned.
I'll tell you now before you even come down here, if your apartment is RD$10,000/month be ready to fork over RD$40,000 for the deposit, first month, finders fee, contract, and anything else that may pop up.
