Thank you everybody for your replies. I eventually found the website (I don't seem to be allowed to post the website here). The rate on the site are still the old ones. I phoned the Direcci?n General de Migraci?n on the telephone number found on the site, 809-508-2555, and yes the rates have gone up. The rates that I posted a few days ago are correct. So as of the 31st of October 2014, the rates are as follow:
De 1 dia a 3 meses RD$2,500.00
De 3 a 9 meses RD$4,000.00
De 9 a 12 meses RD$5,000.00
De 12 a 18 meses RD$6,500.00
De 18 a 24 meses RD$8,000.00
De 24 a 30 meses RD$9,500.00
De 30 a 36 meses RD$11,000.00
Thank you.
