Immigrant Visas for all of South Africa are processed at the Consulate General in Johannesburg. For petitioners residing in the Cape Provinces or KwaZulu Natal, payment of the I-130 petition filing fee can be made at the Consulates General in Durban and Cape Town, after which the petitioner may send the completed I-130 directly to the USCIS office in Johannesburg. All immigrant visa applicants must appear in person at the Consulate General in Johannesburg for an interview once their petition is approved by USCIS.
In general any applicant for an immigrant visa, other than a Diversity Visa, must be the beneficiary of an approved petition. For complete details on petition requirements, please contact: firstname.lastname@example.org
