When starting the IR1 visa process, many doubts arise, especially regarding documentary and identification issues, such as the use of the sponsor”s last name. It is important to emphasize that the main focus of the IR1 visa analysis is to prove the validity and truthfulness of the marital relationship, not the alignment of last names.

There is no legal requirement in the United States for the immigrant spouse to adopt the sponsor”s last name. In other words, you can keep the last name that appeared on your birth certificate or previous documents, as long as there is consistency and clarity in the relationship between the information presented.

If there is a discrepancy between the last names, what really matters is that you demonstrate, with evidence such as the marriage certificate or other official documents, that the marital relationship is genuine and that both names refer to the same individuals mentioned in the process. In some situations, an explanatory statement may be useful to clarify these differences to immigration officers.

I always emphasize the importance of strictly following United States immigration laws and being aware of possible deceptive offers that may appear on the internet or in marketing campaigns. Getting information from official sources and recognized specialists is essential to avoid scams and ensure that you comply with all requirements safely and transparently.

Keeping your documents consistent and correct can facilitate the process, but remember: the choice to adopt or not the sponsor”s last name should be a personal decision, without direct impact on the evaluation of your immigration application, as long as the marital relationship is properly proven.
