how long will be from an ameican sister to invite unmarried brother to usa

July 7, 2026

For a U.S. citizen sister sponsoring her unmarried brother, the total wait is usually well over 10 years , and in some cases 15+ years , depending mainly on the brother’s country of birth and annual visa backlogs.

Quick Scoop

Question: “How long will it be for an American sister to invite her unmarried brother to the USA?”
Short answer:

The sister files Form I‑130 (Sibling, “F4” category).

I‑130 approval: about 6–12 months or more.

Then the long wait: immigrant visa backlog for siblings is often 6–13+ years , sometimes longer for countries with heavy demand (like India, Mexico, Philippines).

So overall, many siblings wait 10–20 years from filing until they can actually move.

This is because brothers/sisters of U.S. citizens are one of the slowest family categories , with a yearly visa cap and a huge queue.

Who Can Apply?

The sister must be a U.S. citizen , not just a green card holder.

She must be at least 21 years old.

The brother can be married or unmarried , but you asked about unmarried.

They must show a real sibling relationship (same parents, or legal step/half-sibling with proper documents).

If the sister is only a permanent resident (green card) , she cannot sponsor a sibling; she must first naturalize as a U.S. citizen.

Step-by-Step Timeline (Realistic)

File I‑130 (Petition for Alien Relative)
- Sister files Form I‑130 to start the case.

 * This creates a **priority date** (your place in the queue).

USCIS I‑130 Processing
- Many law firm guides say about 6–12 months on average , but it can be longer depending on USCIS workload and completeness of documents.

Waiting for Visa Number (F4 Sibling Category)
- After approval, the case goes to the National Visa Center and waits until the priority date is “current” in the U.S. Visa Bulletin.

 * For the F4 sibling category, immigration lawyers report **visa waits from roughly 6 up to 13+ years** , with some countries facing even longer delays.

Consular or Green Card Processing
- Once the date is current, the brother completes visa forms, pays fees, attends medical exam, and has an interview at a U.S. consulate.

 * If approved and entering from abroad, he becomes a **lawful permanent resident (green card holder)** when he arrives in the U.S.

Why It Takes So Long

Sibling category (F4) is not “immediate relative,” so it has annual numeric limits.

Thousands of families apply each year, creating a huge backlog.

Some countries have extra demand , so their waiting lines are even longer than the global average.

Because of this, many attorneys say there is no fast way to bring a sibling ; the best approach is simply to file early and wait.

Can the Brother Visit While Waiting?

While the immigrant petition is pending, some sources note the brother may still try for a temporary visitor visa (B‑2) to come for short visits, but he must show he plans to return home and not immigrate on that visa.

Approval of such a visitor visa is not guaranteed and depends on the consulate’s judgment.

Practical Example

Imagine:

Sister files I‑130 in 2026.
I‑130 is approved in 2027 (about 1 year).

For a typical high‑demand country, the F4 backlog might put his priority date to become current around 2036–2040 , depending on the Visa Bulletin movement.

So the brother might realistically move around 10–15 years after filing, possibly longer.

Key Points in Simple Words

Yes, an American sister can sponsor her unmarried brother.
It is possible , but very slow.
Think in terms of decades, not years : often 10–20 years total waiting time, depending on country and backlog.

There is no shortcut category for siblings, unlike spouses or minor children.

Always consider speaking with a qualified immigration lawyer to check exact current wait times and options based on your specific country and situation.
