ExcellentTravel Try to pay your rent in cash when the owner is in a different country. And some wire transfers are very expensive too, depends of the location of the banks.
There is no dental clinic dedicated to DTV. Just find a dentist and ask him to give you a schedule for your treatment (at least 6 months) with all the detail and cost. Also a date for your 1st appointment and a letter that says you are under their care. Add all the docs to your request and that's it!
