Consular Processing
Applying for a visa or a Green Card in a foreign country through the local U.S. consulate or embassy. For example, when a U.S. citizen marries a non-citizen in a country other than the U.S., the non-citizen will need to apply for the Green Card in that country using consular processing.
In the DV lottery consular processing refers to the verification of details and identity done with the nearest U.S. consulate to the selected individuals’ geographic location.
