Try this link to start. under the C's there is a listing for careers. Don't know if this is the correct place to start. But isn't the Consulates a part of the State Department?
I tried going through the State Dept. and they told me to call the US Embassey or Consular directly? Does anyone have any more info? Calling the 809 221 2171 is a night mare and they never have any information.
