The K-3 visa was created to facilitate the entry of the foreign spouse of a United States citizen while the main immigration process is still underway. This visa allows the couple to stay together while the adjustment of status or immigrant process is finalized.

Together with the K-3, there is the K-4 visa, which is intended for the minor and unmarried children of the K-3 beneficiary. Answering your question: if the spouse applying for the K-3 visa has children from a previous relationship, they can, indeed, apply for the K-4 visa, provided they meet the requirements established by immigration law.

Typically, the requirements for the K-4 visa include: being a biological, adopted, or, in some cases, legally stepchild; being under 21 years old; being unmarried and considered a dependent. Each case is reviewed individually, and proving the family relationship with proper documentation is essential.

For children from the first marriage, it is crucial to demonstrate the legal relationship with the spouse interested in the K-3 visa so that the consulate or USCIS accepts their inclusion as beneficiaries. It is fundamental to strictly follow the US immigration laws, seek information from reliable sources, and avoid miracle promises.

Ensuring correct documents prevents delays and complications. In case of doubts, it is recommended to consult official sources and be cautious against scams.
