Determine your visa category: Identify the appropriate immigrant visa category, such as family-sponsored, employment-based, or diversity visa (DV) lottery.

The DV-2 visa is a diversity visa that allows certain beneficiaries to accompany or follow-to-join a principal diversity visa holder in the United States. It is intended for spouses and children of DV-1 visa holders who have been granted immigrant visas through the diversity visa lottery program. It is important to note that the DV program grants immigrant visas, not temporary visas.

The DV3 visa is not a specific type of visa. It appears to be a typographical error or misinformation. It is possible that the intended term is DV-3 visa, which refers to a visa category under the Diversity Immigrant Visa Program. This program allows individuals from countries with low rates of immigration to the United States to apply for immigrant visas.
