Can a Child Apply for a Parent’s Green Card? I-130 and Affidavit

To apply for a parent’s green card, a U.S. citizen who is at least 21 years old files Form I-130 (Petition for Alien Relative) with U.S. Citizenship and Immigration Services. Parents of adult citizens are classified as “immediate relatives,” so there is no annual cap and no visa waiting list, which makes this one of the faster family-based routes to permanent residence.¹ From there, the parent either adjusts status inside the United States or completes consular processing abroad, and along the way you have to document the relationship, sign a binding financial sponsorship, and get the parent through a medical exam.

Who Can File

Only U.S. citizens can sponsor a parent. Lawful permanent residents cannot; they have to naturalize first. The petitioning child must be at least 21 on the date the petition is filed, and filing earlier will be rejected outright.¹ How you became a citizen (birth in the U.S., birth abroad to citizen parents, or naturalization) makes no difference. You can sponsor both parents, but each one needs a separate I-130 and a separate Affidavit of Support.

Proving the Parent-Child Relationship

USCIS wants documentary proof that the relationship is real. What counts depends on how the relationship was formed.

For a biological mother, a birth certificate listing both names is usually enough.²
For a biological father, the birth certificate showing the father’s name is the starting point. If the child was born outside of marriage, expect to add evidence of a genuine relationship, such as records of financial support or shared residence.²
For a stepparent, the marriage that created the relationship must have taken place before the child turned 18. You’ll need the marriage certificate and proof that any prior marriages legally ended.³
For an adoptive parent, the adoption must have been finalized before the child turned 16, and the child must have lived in the adoptive parent’s legal custody for at least two years, which do not have to be continuous.⁴

Every foreign-language document needs a certified English translation. If a birth certificate is unavailable, USCIS will look at secondary evidence like religious records, school records, or sworn affidavits, but you should explain why the primary document can’t be produced. In some cases USCIS asks for AABB-accredited DNA testing to confirm a biological link, which typically runs $400 to $800.

Filing Form I-130 and Choosing the Path

The process starts with Form I-130, which establishes the qualifying relationship. The filing fee is $625 online or $675 on paper.⁵ What comes next depends on where the parent is.

If the Parent Is Already in the United States

A parent who was lawfully admitted or paroled, meaning they entered through an official port of entry with inspection, can file Form I-485 (Application to Register Permanent Residence or Adjust Status) at the same time as the I-130. This concurrent filing lets your parent remain in the country while the case is decided.⁶ Because parents of citizens are immediate relatives, a visa number is always available, so there is no queue.⁷ The I-485 fee is $1,440 for applicants age 14 and older.⁸

If the Parent Is Abroad

Once USCIS approves the I-130, it sends the case to the National Visa Center. The NVC sends a welcome letter and instructions to use its online portal, where your parent submits Form DS-260 (the immigrant visa application) along with financial and civil documents such as birth and marriage certificates.⁹ After the NVC accepts the file, it schedules an interview at the U.S. embassy or consulate in the parent’s country. Your parent should bring originals or certified copies of every civil document, photographs, police certificates, and the sealed medical envelope from the panel physician; a missing item can force a second appointment.¹⁰ If your parent fails to apply for the visa within one year of being notified of availability, the petition may be terminated.

The Affidavit of Support

Every petitioner files Form I-864 (Affidavit of Support), a legally binding contract with the U.S. government promising to support the parent financially. Your annual household income has to reach at least 125% of the Federal Poverty Guidelines for your household size. For 2026, the minimum for a household of two in the 48 contiguous states is $27,050, with higher figures in Alaska ($33,813) and Hawaii ($31,113); each additional household member adds $7,100 in the contiguous states.¹¹ Submit your most recent federal tax return with all W-2s and 1099s, and add an employment letter and recent pay stubs to show current earnings.¹²

If your income doesn’t clear the threshold, you can either bring in a joint sponsor (any U.S. citizen or lawful permanent resident who independently meets the requirement and agrees to share the obligation) or use assets. For a parent case, assets must be worth at least five times the income shortfall.¹²

The obligation you take on by signing is serious. It lasts until your parent becomes a U.S. citizen or is credited with 40 qualifying quarters of work (roughly ten years). It doesn’t end if your finances change or the relationship sours, and if your parent receives certain government benefits during that time, the paying agency can seek reimbursement from you.¹²

The Medical Exam

Every parent applying for a green card has to complete an immigration medical exam. Inside the United States, that means a USCIS-designated civil surgeon; abroad, it means an embassy-authorized panel physician in the country where the interview will happen.¹⁰ The doctor completes Form I-693 (Report of Immigration Medical Examination and Vaccination Record), which screens for communicable diseases and certain physical or mental health conditions. Your parent will also need proof of required vaccinations or receive missing doses at the appointment. The list includes measles, mumps, rubella, hepatitis A and B, tetanus, and others depending on age.¹³ As of December 2024, Form I-693 must be filed together with Form I-485; filing the adjustment application without it may result in rejection.¹⁴

If the Parent Entered Without Inspection

This is where families most often get caught by surprise. Federal law requires that anyone adjusting to permanent resident status inside the United States must have been “inspected and admitted or paroled” at entry.¹⁵ Immediate relatives are excused from some bars, like adjusting after falling out of status or working without authorization, but not from this one.¹⁶

A parent who crossed the border without inspection generally cannot adjust status in the United States and would need to leave for consular processing. But departing after unlawful presence triggers re-entry bars: three years if the parent was unlawfully present for more than 180 days but less than a year, or ten years if unlawfully present for a year or more.¹⁷

A waiver exists for parents who can show that a U.S. citizen or permanent resident spouse or parent (not child) would suffer extreme hardship if the waiver were denied. The provisional unlawful presence waiver, Form I-601A, lets the parent get that waiver approved before leaving, which shortens the separation.¹⁸ Note that the qualifying relative for the hardship showing cannot be the U.S. citizen child who filed the petition.

What Happens After You File

USCIS sends a Form I-797C (Notice of Action) confirming receipt and giving you a case number you can track online.¹⁹ If your parent filed an I-485 in the U.S., USCIS will schedule a biometrics appointment for fingerprints and photographs used in background checks.

USCIS may call the parent in for an interview at a local field office, but parents of citizens are among the categories eligible for an interview waiver on a case-by-case basis. An officer reviews the file, and if everything is well-documented, the case may be approved without one.²⁰ If an interview is held, the officer confirms the relationship and the parent’s admissibility.

While the I-485 is pending, your parent can file Form I-765 for an Employment Authorization Document to work legally,²¹ and Form I-131 for advance parole, a travel document that permits leaving and re-entering without abandoning the application. Leaving the country without advance parole while I-485 is pending will generally cause USCIS to treat the application as abandoned.²²

Timing shifts by office. As a rough benchmark, the national median processing time for I-130 petitions in the immediate relative category was about 11 months in fiscal year 2024, and the median for family-based I-485 applications was about 9.4 months in the same period.²³ Concurrent I-130/I-485 filing overlaps much of the work. Consular processing adds NVC review and embassy scheduling on top.

Grounds That Can Still Block Approval

Even with a solid petition and a real relationship, a parent can be denied on inadmissibility grounds. The categories that come up most often are:

Health: communicable diseases of public health significance (such as active tuberculosis), missing required vaccinations, physical or mental disorders associated with harmful behavior, and drug abuse or addiction.
Criminal history: convictions for crimes involving moral turpitude, drug offenses, multiple convictions with aggregate sentences of five years or more, and involvement in drug trafficking, human trafficking, or money laundering.
Fraud or misrepresentation in trying to obtain an immigration benefit.
Unlawful presence, which triggers the three-year or ten-year bars described above.¹⁷
Security concerns, including involvement with espionage, terrorism, or efforts to overthrow the government.

Waivers are available for some grounds. Health issues can often be resolved by finishing treatment or getting the missing vaccines, and unlawful presence bars can sometimes be waived through Form I-601 or I-601A. Criminal and security-based inadmissibility is harder to overcome and is worth reviewing with an immigration attorney before filing.
