If all documents are collected and the consular officer grants the visa, the visa itself will be put in the passport and the applicant will receive the packet for the Bureau of Immigration and Citizenship. To enter the United States on a K3/K4 visa, you must have both the visa itself in your passport and the packet for the Bureau of Immigration and Citizenship.
Individuals who enter the U.S. with a valid K3 non-immigrant visa will be allowed to stay in the U.S. for 2 years. A child who is entering the United States on a valid K4 non-immigrant visa will be authorized to remain in the United States for two years or until the child turns 21, whichever is shorter. After two years of authorized stays, K3 and K4 visa holders may apply to the Bureau of Immigration and Citizenship for an extension of stay, using Form I-539. The period of stay is extended at intervals of 2 years. When the pending immigration petition is approved, individuals who are in the United States on K3/K4 visas may change their status to permanent resident under certain conditions.
