When starting an immigration process to the United States, such as the K-3 visa, it is essential to understand which documents are accepted by the American authorities for identity verification. Usually, the required documentation includes a valid passport and other official papers issued by the government of the country of origin.

These documents must comply with the norms of the United States Citizenship and Immigration Services (USCIS). In the case of documents like CPF, RG, DNI, or other types of foreign identification, it is important to know that they can serve to prove your identity in your home country, but for immigration purposes, they alone do not replace the passport or other official document required by U.S. law.

Generally, the passport is the main document used to identify and verify the personal information of applicants. In some cases, additional information may be presented as a complement, but always accompanied by the passport or equivalent document, duly translated and, if necessary, authenticated.

Therefore, even though CPF, RG, DNI, and other similar documents are very useful in your country, when preparing an immigration application for the U.S., it is wise to pay attention to the specific USCIS requirements. Following the official rules and guidelines is vital to avoid future problems.

Always check for updated information on the official USCIS website and inquire about confirmed procedures to avoid scams or misleading advertisements that promise easy solutions. Remember that although it is possible to use documents from the country of origin as support, the main identification document accepted for the K-3 visa remains the valid passport. If doubts arise, consulting reliable resources or seeking specialized guidance-without compromising your privacy-can help you conduct the process correctly and safely.
