The F2B category, within the United States Family Based visa system, is specifically aimed at unmarried sons and daughters – that is, without marital ties – of legal permanent residents (green card holders) who are 21 years of age or older.

In other words, if the resident”s son or daughter is under 21 years old and unmarried, they generally fall under another category, known as F2A. This differentiation is important because the U.S. immigration system organizes family preferences to recognize the different relationships and needs of immigrants.

The F2B was created precisely to address the demand from adult sons and daughters who are direct dependents of residents, thereby providing a path that, despite wait times, allows them to pursue permanent residence in the United States.

Always keeping in mind the complexity and constant updates of immigration laws, it is essential to strictly follow the rules established by the U.S. government. If doubts arise or assistance is needed to better understand the process, consulting reliable sources or seeking guidance from professionals specialized in immigration is a safe way to avoid scams and marketing campaigns promising guaranteed results in a simplified manner.

Staying well informed and acting according to legal guidelines is fundamental to achieving success in any immigration process. I hope this information has clarified your question about F2B and helps in understanding the system as a whole.
