Brothers and sisters of U.S. citizens age 21 and over fall under the F4 preference category. Step-siblings can qualify under this preference if the marriage creating the step-child relationship of each sibling to the stepparent took place before the step-child’s 18th birthday.
The waiting period to immigrate to the U.S. for brothers/sisters of adult U.S. citizens is quite lengthy and U.S. citizens should consult with our firm to determine if this the best option for the sibling before filing.
