How to bring my son to the U.S.

With today’s immigration landscape, many parents and lawful permanent residents are looking for clear answers on how to bring my son to the U.S. The process typically starts by filing Form I-130 with USCIS.

That said, wait times, preference categories, and requirements vary based on key factors, including your immigration status and your child’s marital status.

At Curbelo Law, we help hundreds of families understand this process with clarity. If you need a tailored strategy, you can speak with immigration attorney Carolina Curbelo, the daughter of Cuban refugees, who understands firsthand the challenges many immigrant families face in the United States.

What I need to know in 2026 about how to bring my son to the U.S. as a U.S. citizen or lawful permanent resident

If you are a lawful permanent resident (green card holder) or a U.S. citizen, you can petition for your child in many situations, but not every case moves the same way. Immigration law distinguishes between:

• Children under 21 and children 21 or older.
• Unmarried children and married children.
• Petitioners who are U.S. citizens vs. lawful permanent residents.

Those three variables can completely change the immigration category, the expected wait time, and which forms you may need.

How does the process start?

In most cases, the process begins with a U.S. family-based immigration petition. From there:

• If your child is in the United States and the law allows them to adjust status at that time, they may be able to file Form I-485.
• If your child is outside the country, the case will typically move through consular processing.

What must you prove to petition for your child?

To sponsor your child, you generally must show:

• That you are a U.S. citizen or a lawful permanent resident.
• That a valid parent-child relationship exists.
• Your child’s age and marital status, because these determine the visa category.
• If annual limits apply, that your priority date is current under the Visa Bulletin.

The difference between U.S. citizens and green card holders

If you are a U.S. citizen, your unmarried children under 21 are often considered immediate relatives. As a result, they usually do not have to wait for a visa number to become available.

If you are a lawful permanent resident, your children are not classified as immediate relatives, so they typically depend on visa availability and longer wait times.

What documents do I need to start the petition?

In addition to Form I-130, USCIS requires evidence of both the family relationship and your immigration status. The exact documentation depends on the type of child and how the legal relationship was established.

If you are a U.S. citizen, you should submit at least one of the following:

• U.S. birth certificate.
• Valid U.S. passport.
• Certificate of Naturalization.
• Certificate of Citizenship.

If you are a lawful permanent resident:

• A copy of the front and back of your green card, or valid temporary proof of permanent residence.

To prove the parent-child relationship:

• Your child’s birth certificate showing the relationship.
• If applicable, marriage certificates, divorce decrees, court orders, or adoption decrees that document name changes or the legal relationship.

One key point is not to assume “under 21” means “easy.” Even when a child is under 21, you still have to evaluate whether the category is immediate or preference-based, whether the child is inside or outside the United States, and whether they may qualify to adjust status or must proceed through consular processing.

Who can petition for a child based on immigration status

If you are a U.S. citizen

• You can petition for unmarried children under 21.
• You can petition for unmarried children who are 21 or older.
• You can petition for married children of any age.

When your child is unmarried and under 21, they are typically considered an immediate relative. 

By contrast, adult children or married children fall into family preference categories and must wait for a visa number to become available under the Department of State’s monthly Visa Bulletin.

If you are a lawful permanent resident

• You can petition for unmarried children under 21.
• You can petition for unmarried children who are 21 or older.
• You cannot petition for married children while you remain a lawful permanent resident.

This is one of the most important points in this guide, and it should be crystal clear. If your child marries while the petition requires them to remain unmarried, the case can become seriously complicated or even lose eligibility. 

In some cases, becoming a U.S. citizen at the right time can change the petition category and improve the options. That is why it can also help to review our content on how to get U.S. citizenship.

Example: A lawful permanent resident files an I-130 for an unmarried 19-year-old child. If the child gets married during the wait, that petition no longer fits the category available to green card holders. In that situation, the petition may no longer work as long as the parent remains a lawful permanent resident.

Which documents change depending on the type of child

Proof of the relationship is not always the same. USCIS distinguishes between biological children, children born out of wedlock, stepchildren, and adopted children. 

In every scenario, the goal is to show that the relationship meets the legal definition of “child” or “son/daughter” under immigration law.

If you are the biological mother

In most cases, the child’s birth certificate issued by the appropriate civil authority will be enough.

If you are the biological father

You may need: 

• The child’s birth certificate, 
• Proof of marriage to the mother, or 
• If there was no marriage, additional evidence of legitimation or a bona fide parent-child relationship, depending on how your case fits under the immigration rules.

If you want to petition for a stepchild

You must prove the marriage to the biological parent and that the stepparent-stepchild relationship was created before the child turned 18. 

It is important to avoid confusion here. Being able to petition for a stepchild does not automatically mean the child derives citizenship through that relationship alone. In many cases, citizenship only applies if there is also a qualifying adoption.

If you are an adoptive parent

In addition to the original birth record and the final adoption decree, it is often essential to prove at least 2 years of legal custody and 2 years of physical custody. 

In more complex international adoptions, a different process may apply instead of a standard I-130 filing.

Illustrative example: In adoption cases or cases involving children born out of wedlock, a mistake in the initial evidence can lead to a Request for Evidence (RFE) or even a Notice of Intent to Deny (NOID).

How to petition for a child who lives inside or outside the United States

Where your child is located changes the legal path the case will follow after USCIS approves the I-130.

If your child is in the United States

You will need to evaluate whether adjustment of status is available and when it can be filed:

• If the child is an immediate relative of a U.S. citizen and meets the requirements, in many cases you may be able to file the I-130 together with the I-485 at the same time.
• If the case is in a preference category, adjustment can move forward only when a visa number is available under the Visa Bulletin USCIS references each month.

If your child is outside the United States

This is not resolved at the consulate from day one. The process follows a sequence:

1. First, you must have an approved I-130 petition.
2. Then, the case is transferred to the National Visa Center (NVC), which coordinates the documentation.
3. Finally, your child attends their immigrant visa appointment at a U.S. consulate or embassy through the Department of State.

You can learn more about that path in our guide to the official immigrant visa process.

How long does all of this take?

There is no single timeline. The real processing time depends on:

• The family category assigned to the case.
• The beneficiary’s country of origin.
• Monthly visa availability in the Visa Bulletin.
• Whether immigration policy changes during the process.
• Whether the case receives RFEs or additional review.

It is not wise to promise fixed timeframes, because processing can vary significantly depending on multiple factors. 

If your child is outside the country, the case does not begin at the consulate. First, the petition must be approved, and then the case moves through the immigrant visa process with the Department of State.

Adult children, preference categories, and age protection

When a child is 21 or older, or when the case is not an immediate-relative case, the petition falls into categories with annual numerical limits. That means the priority date becomes critical for knowing when the case can move forward.

But there is a factor many people do not realize: immigration age does not always match biological age.

What is the CSPA and why does it matter?

The Child Status Protection Act (CSPA) is a law that, in certain situations, allows a child to be treated as under 21 for immigration purposes even after turning 21. To apply it, you typically need to analyze:

• The child’s biological age when the visa became available.
• How long USCIS took to approve the petition (that time is subtracted).
• Whether the child acted quickly to pursue the visa once it became available.

Example: A child approaches age 21 while waiting for the petition to progress. In some cases, the CSPA protects them; in others, it does not. That is why it is important to review dates, categories, and Visa Bulletin movement before assuming the child has aged out.

Conditional residence, appeals, and sensitive situations

If your child’s residence is conditional

When a child’s residence is based on a recent marriage involving the petitioner, conditional residence may apply. In those cases, the conditions are not removed with Form I-90, but with Form I-751.

If USCIS denies the I-130

A denial does not always mean the case is over. Depending on the reason, there may be an option to appeal or file a motion. 

In many I-130 denials, Form I-290B may be involved, but the right strategy depends on the type of decision and the history of the case.

If your child has a complicated immigration situation

When there is unlawful presence, entry without inspection, criminal history, or risk of removal proceedings, filing forms alone is not enough. 

In those scenarios, options such as a waiver of inadmissibility or an immigration appeal may be relevant.

Frequently asked questions when petitioning for a child to come to the United States

When people tell us, “how to bring my son to the U.S.,” many questions usually follow. Below are answers to some of the most common concerns, but keep in mind that every case should be reviewed individually to receive specific legal guidance from an immigration attorney.

Send us your question. It does not commit you to anything, and it can be the first step toward reuniting with your loved ones.

Can I petition for a child who lives outside the United States?

Yes. In most cases, you will file the I-130 and, after approval, the case will be forwarded to the National Visa Center and then to the appropriate consulate or embassy for immigrant visa processing.

Can a lawful permanent resident petition for a married child?

No, not while they remain a lawful permanent resident. Green card holders can petition for unmarried children, but not married children.

How long does it take to petition for an adult child?

There is no single timeline. It depends on the category, the country, case volume, and visa availability. Adult children usually face longer waits than minor children of U.S. citizens.

Can my child get a green card from inside the United States?

It depends on how they entered the country and whether they have a legal path to adjust status once a visa is available for their category. In some cases yes, and in others consular processing is required.

What happens if USCIS denies the petition?

The denial notice will explain the reason. Depending on the facts, there may be an appeal, a motion to reopen, or a different evidence strategy. The key is not to assume all denials are solved the same way.

Immigration lawyers to help you petition for your child

As you have seen throughout this guide, petitioning for your child as a green card holder or U.S. citizen does not follow a one-size-fits-all path. 

Some cases are straightforward, while others become far more technical, especially when the child is 21 or older, married, adopted, a stepchild, entered without inspection, or when visa availability is an issue.

At Curbelo Law, we can help you:

• Identify the correct category based on your status and your child’s situation.
• Evaluate whether your child can adjust status or must proceed through consular processing.
• Prepare complete evidence to avoid delays, RFEs, or denials.
• Support you throughout the process, from the I-130 through final approval.
