Whether or not you can bring your family members with you to the U.S. will depend on several factors, including your immigration status, the type of visa you are applying for, and your relationship with your family members.
If you are applying for a family-based visa or green card, you may be able to bring your spouse and unmarried children under the age of 21 with you to the U.S. You may also be able to sponsor other family members, such as parents or siblings, but the eligibility requirements can be more restrictive.
If you are coming to the U.S. on a work or student visa, your ability to bring family members with you may be more limited. Generally, your spouse and unmarried children under the age of 21 may be eligible for dependent visas, but other family members may not be eligible.
It is important to consult with an immigration attorney to determine your eligibility to bring family members with you to the U.S. based on your individual circumstances and immigration status.
