Family means everything. For many Pakistanis who become US citizens, one dream stays close to the heart: to bring a brother or sister to live beside them in the United States. The US immigration system makes this possible through the F-4 visa. But the path is long, the rules are strict, and the misunderstandings run deep.
I have guided many families through this exact journey. My name is Mujtaba Maharvi, and I run Westside Visa Consultants. In this guide, I explain the F-4 visa in plain language. I walk you through who qualifies, how the process works, and the honest truth about the wait. Most of all, I clear up the common problems and misunderstandings that cost families years of confusion.
What is the F-4 visa?
The F-4 visa is the fourth preference family-based immigrant visa. It lets an adult US citizen sponsor a sibling: a brother or a sister. Once the process finishes, your sibling enters the United States as a lawful permanent resident and receives a green card.
Notice the word “immigrant.” This is not a visit visa. The F-4 leads to permanent residence, not a short trip. Your sibling comes to live in the US for good, with the right to work and, in time, to apply for citizenship.
Key point
Because the fourth preference faces a yearly limit, demand far outpaces supply. That single fact shapes everything about this journey, especially the wait.
Who can sponsor, and who counts as a sibling?
Let me start with the sponsor. Only a US citizen aged 21 or older can file an F-4 petition for a sibling. This point matters: a green card holder cannot sponsor a brother or sister. You must hold full US citizenship first.
Now the sibling. The law recognises a sibling relationship through a shared parent. In most cases, that means you and your sibling share at least one common parent. This covers full siblings, and it can also cover half-siblings, step-siblings, and adopted siblings, as long as you prove the legal relationship with the right documents.
Your sibling’s own family can join too. When your brother or sister immigrates, their spouse and their unmarried children under 21 can usually come along as derivative applicants. So one petition can, over time, reunite a whole household with you in the United States.
How the F-4 process works, step by step
The F-4 journey runs through several clear stages. Each one takes time, so it helps to know the full map before you start.
1
File Form I-130
You, the US citizen, file Form I-130 (Petition for Alien Relative) with USCIS. The day USCIS receives it becomes your sibling’s priority date; remember it, because it decides your place in the queue.
2
Wait for the priority date
After USCIS approves the petition, the long wait begins. Your sibling joins a worldwide line, and a visa only opens when their priority date reaches the front. You track this through the monthly Visa Bulletin.
3
National Visa Center processing
Once a visa looks close, the case moves to the NVC. You pay fees, submit the DS-260 application, and upload civil and financial documents, including the Affidavit of Support (Form I-864).
4
The interview
Your sibling attends an interview at the US Embassy or Consulate in Pakistan (usually Islamabad). The officer checks the documents, confirms the relationship, and decides the case.
5
Immigrant visa & green card
After approval, your sibling receives an immigrant visa, travels to the US, and becomes a permanent resident. The physical green card follows soon after.
The honest truth about the wait
Here is the part I never sugar-coat: the F-4 visa involves one of the longest waits in the entire US immigration system.
The reason is simple maths. The law caps the fourth preference at roughly 65,000 visas a year for the whole world, plus any unused numbers from higher categories. Millions of siblings want them. So the line stretches back many years.
Typical wait from filing to visa
~17 years for applicants from Pakistan
Based on the July 2026 Visa Bulletin. Pakistan falls under “all other countries,” now processing priority dates around early 2009. Waits shift over time.
I share these numbers not to discourage you, but to prepare you. Families who understand the timeline plan well. They file early, they keep the case alive, and they avoid painful surprises. Families who expect a quick result feel crushed when reality hits. Knowledge is your best tool here.
Common problems and misunderstandings
Over the years, I have seen the same myths cause the most heartache. Let me clear up the ones I hear most often.
The myth“A green card holder can sponsor a sibling.”
The realityOnly a US citizen aged 21 or older can file an F-4 petition. Green card holders must naturalise first.
The myth“The petition lets my sibling wait inside the US.”
The realityFiling Form I-130 gives no status, visa, or right to live or work in the US. Your sibling waits in Pakistan.
The myth“It only takes a year or two.”
The realityThe realistic wait runs well over a decade, often 17 years or more. Anyone promising a fast F-4 is not being truthful.
The myth“Today’s wait time is exactly what I’ll get.”
The realityThe line can grow or shrink over the years. Treat today’s figure as a guide, not a guarantee.
The myth“I can add my sibling’s married or older children.”
The realityOnly your sibling, their spouse, and unmarried children under 21 can immigrate. Others may “age out.”
The myth“Cousins, in-laws, aunts and uncles count too.”
The realityThe F-4 covers only brothers and sisters through a shared parent; no cousins, in-laws, or other relatives.
The myth“The case continues no matter what happens.”
The realityIf the petitioner dies or loses citizenship, the petition can fail. Never assume it survives on its own.
The documents you will need
Strong documents make or break an F-4 case, especially proof of the sibling relationship. Gather these early and keep them safe.
- The US citizen’s proof of citizenship: passport, naturalisation certificate, or birth certificate.
- Both siblings’ birth certificates naming at least one common parent; this is the heart of your evidence.
- For half or step-siblings, the relevant parents’ marriage certificates.
- At the NVC stage: police certificates, medical records, and the financial Affidavit of Support.
Watch out
When names or dates differ across documents, or a birth certificate is missing, the case slows down. This is exactly where careful preparation pays off.
Tips from a visa expert to protect your case
A journey this long needs care from start to finish. Here is what I tell my own clients.
File as early as you can
Every month counts in a queue this long. A clean, correct I-130 locks in your priority date sooner.
Keep your case alive
Always update USCIS and the NVC when you move or change email, so you never miss a vital notice.
Watch the children’s ages
Keep the aging-out risk in mind. The Child Status Protection Act sometimes helps; understand how it applies.
Stay consistent and honest
Keep names and dates identical across every form. Never hide a past issue; honesty protects you.
Track the Visa Bulletin
Check it a few times a year so you always know where the line stands. When your date gets close, move quickly on the NVC steps.
Why expert guidance matters for the F-4 journey
An F-4 case can outlast jobs, house moves, and even other visas. Over such a long stretch, small mistakes grow into big problems: a weak relationship document, a missed NVC notice, a child who ages out unexpectedly. Any one of these can cost you years or the whole case.
This is where experienced guidance earns its value. A seasoned consultant files a clean petition, builds strong relationship evidence, and keeps your case on track across the entire wait. We watch the Visa Bulletin for you, prepare you for each stage, and help you avoid the traps that catch unprepared families. On a journey measured in years, steady expert support is not a luxury; it is protection for your family’s future.
