You cannot begin an application for an immigrant visa at The U.S. Consulate General Rio de Janeiro, or other Posts. The process for all immigrant visas, other than the Diversity Visa Lottery process, begins with the Department of Homeland Security (DHS)/U.S. Citizenship and Immigration Service (USCIS). The family member or employer in the U.S., through whom you wish to qualify, must begin the process by filing an I-130 petition or I-129F Fiancé petition, or the I-140 employment petition with the DHS/USCIS office in the United States, as per the instructions on the forms.
