If you do not qualify as an immediate relative of a U.S. citizen, you may be in what is called a family preference category. These are:
- FB1 – Unmarried sons and daughters over the age of 21, and their children
- FB2 – Spouses of Lawful Permanent Resident (Green Card Holder)
- FB3 – Married sons and daughters of U.S. citizens
- FB4 – Siblings of U.S. citizens
These types of immigrant classifications involve specific, more distant, family relationships with a U.S. citizen and some specified relationships with a Lawful Permanent Resident. Congress has limited the number of relatives who may immigrate under these categories each year so there is usually a waiting period before an immigrant visa number becomes available, unlike immediate relatives who have no waiting list or numerical limitations. The wait times are based on various factors and are determined by the preferences below, such as your nationality and wait times for applicants born in India, Mexico, the Philippines, and mainland China are particularly long.
