i need help with paperwork for getting married in the Dominican Republic

Are you referring to immigration paperwork or paperwork needed to get married? If you are referring to immigration paperwork, you can only start the process once married. It is a two-step process. You will first need to file an immigrant visa petition on his behalf. Once the petition is approved, your spouse will apply for an immigrant visa.

If, however, you need assistance with paperwork to marry, you should contact the Dominican Republic's consulate.
