The F4 visa is intended for brothers and sisters of United States citizens and requires proof of a legitimate family relationship between the petitioner and the beneficiaries. As a rule, for the sibling relationship to be recognized by immigration authorities, it is necessary to have consistent documentation confirming this connection, usually through birth certificates that prove the siblings share at least one parent.

When each sibling has completely different parents – that is, there is neither a father nor a mother in common – it will hardly be possible to demonstrate a blood or legal connection that meets the established requirement for the F4. Even in cases of half-siblings (those who share only one parent), it is essential to have clear and robust evidence of this relationship, according to civil records or other official documents. Therefore, if there is no documentary element proving a recognized family bond (whether by biological ties or legal adoption), the application for the F4 visa may be compromised.

It is always important to strictly follow the United States immigration laws and keep documentation in perfect order. Given the complexity of the system and the risk of fraud, it is advisable to seek specialized guidance from experienced professionals and trusted sources, thereby avoiding scams and marketing campaigns that promise miraculous solutions. This caution will help prevent unpleasant surprises in the process and ensure that the requirements are truly met.
