Filipinos would require a tourist visa when visiting the country of Dominican Republic, except when you hold a visa to enter the United States, Canada, or any European country. Should this be the case, you will only need to purchase a tourist card prior to entry to the country. You can purchase this tourist card in the embassy.
If you do not have a visa to those aforementioned countries, you will need to apply for a tourist visa or a business visa as the case may be. For more information you may contact:
