I'm a U.S. citizen, and my mother has a green card. I want to bring my married brother, who has three children, to the United States. What is the easiest way to do this?
Attorney Answer
As a U.S. citizen, you can petition for your married brother and his children, but this falls under federal immigration law rather than Florida law, and it helps to know upfront that this category has some of the longest wait times in the entire immigration system. Siblings of U.S. citizens fall under the family fourth preference category, F4, under Section 203(a)(4) of the Immigration and Nationality Act. Only a U.S. citizen who is at least 21 years old, not a green card holder, can file this type of petition, so your mother's status doesn't help here, though it may matter for other family members down the road.
The process starts with filing Form I-130, Petition for Alien Relative, with U.S. Citizenship and Immigration Services. Once approved, your brother is assigned a priority date, essentially his place in line, and he has to wait until that date becomes current under the State Department's monthly visa bulletin before he can apply for a visa. For the sibling category, current wait times are commonly measured in well over a decade, and can be longer depending on your brother's country of birth.
If your brother is married, his wife can generally be included as a derivative beneficiary. Children who are unmarried and under 21 when the visa becomes available can generally be included as well, but a child who marries or turns 21 before then may fall out of the case or need separate handling, sometimes with some protection under the Child Status Protection Act depending on timing.
What you can do
1. File Form I-130 for your brother as soon as you're ready, since the wait clock starts running from the date USCIS receives it. 2. Gather proof of your citizenship and your relationship to your brother, such as birth certificates showing you share a parent. 3. Track the visa bulletin over time to watch your brother's priority date. 4. Ask an immigration attorney whether the Child Status Protection Act could help protect any of his children's eligibility if they're close to turning 21.
This is general legal information, not legal advice. An immigration attorney can confirm current wait times for your brother's country and help make sure the petition is filed correctly the first time.

Frequently Asked Questions
How long does it typically take to bring a sibling to the U.S. as a citizen?
The sibling category, F4, is the slowest family-based category, and current wait times commonly run well over a decade, longer for some countries. Filing the petition now is worthwhile even with a long wait, since your brother's place in line is set by the date USCIS receives it.
Can my mother, who has a green card, sponsor my brother instead?
No. Only a U.S. citizen who is at least 21 years old can petition for a sibling under immigration law. Green card holders can only petition for a spouse or unmarried children, not siblings, so this route has to go through you as the citizen.
Will my brother's wife and children be included in the petition?
Generally yes, his wife and any unmarried children under 21 can be included as derivative beneficiaries when the visa becomes available. A child who marries or turns 21 before that point may need separate handling, so it's worth discussing timing with an immigration attorney as the case moves forward.
