If you are a 21-year-old U.S. citizen, you can petition your parents for a Green Card, and parents sit in the most favorable family-based category the immigration system offers. As “immediate relatives,” they face no annual visa cap and no waiting list for a visa number. Once U.S. Citizenship and Immigration Services (USCIS) approves the petition, a visa is available right away.1U.S. Citizenship and Immigration Services. Visa Availability and Priority Dates The real work is paperwork, proving you can financially support your parent, and navigating a few traps that can turn a straightforward case into a hard one.
Why Parents Skip the Waiting List
Family-based Green Card categories split into “immediate relatives” and “preference categories.” Preference categories have annual caps and can back up for years. Immediate relatives do not. Parents of U.S. citizens aged 21 or older fall into the immediate relative group along with spouses and unmarried children under 21.2U.S. Citizenship and Immigration Services. Green Card for Immediate Relatives of U.S. Citizen The only wait is USCIS processing time, which has recently averaged around 14.5 months for the initial petition.
Which Parents You Can Petition
The petition covers more than biological mothers. The qualifying relationships and the documents each one needs:
- Biological mother. Your birth certificate showing her name is usually all you need.
- Biological father, if your parents were married. Provide your birth certificate showing both parents’ names, plus their civil marriage certificate.3U.S. Citizenship and Immigration Services. Bringing Parents to Live in the United States as Permanent Residents
- Biological father, if your parents were not married. If he legally legitimated you before your 18th birthday, you provide evidence of that legitimation. If he did not, you must show a real emotional or financial bond existed between you and him before you turned 21 or got married, whichever came first.
- Adoptive parent. The adoption must have been finalized before you turned 16. You need a certified copy of the adoption decree and a statement showing when and where you lived together.
- Step-parent. The marriage between your step-parent and your biological parent must have taken place before you turned 18. Provide the marriage certificate plus proof that any earlier marriages ended legally.
The out-of-wedlock father category catches people off guard. A name on a birth certificate is not enough on its own. Letters, photos, money transfer receipts, and phone records help build the parent-child bond USCIS wants to see.
The Form I-130 and What Proves Your Case
Every petition starts with Form I-130, Petition for Alien Relative, filed with USCIS.4U.S. Citizenship and Immigration Services. I-130, Petition for Alien Relative Along with the form, you have to prove two things: that you are a U.S. citizen, and that the person you are petitioning is actually your parent.
To prove citizenship, include one of the following:
- A copy of your U.S. birth certificate issued by a civil authority
- A copy of your naturalization or citizenship certificate
- A copy of your Consular Report of Birth Abroad (Form FS-240)
- A copy of your unexpired U.S. passport
To prove the relationship, the specific documents depend on which category above matches your situation. Your birth certificate is the baseline. Depending on the relationship, you may also need marriage certificates, adoption decrees, divorce decrees or death certificates ending prior marriages, and evidence of legitimation or bond.5USCIS.

How to File and What It Costs
You can file Form I-130 online through a USCIS account or by mailing a paper form to the appropriate USCIS lockbox. The correct mailing address depends on where you live and whether your parent will file for adjustment of status at the same time.
The filing fee is $625 online or $675 by mail. A payment change took effect on October 28, 2025: USCIS no longer accepts personal checks, business checks, money orders, or cashier’s checks for paper filings. If you file by mail, you pay by credit, debit, or prepaid card using Form G-1450, or by direct bank account transfer using Form G-1650. Online filers pay through the USCIS portal.6U.S. Citizenship and Immigration Services. USCIS to Modernize Fee Payments with Electronic Funds
Once USCIS receives your petition and fee, you get a receipt notice (Form I-797C) with a case number. You use that number to check status online.
Financial Support: The Hurdle Most 21-Year-Olds Feel
Before your parent gets a Green Card, you must file Form I-864, Affidavit of Support, which is a legally enforceable promise to the U.S. government that you will financially support your parent so they do not fall onto public benefits.7U.S. Citizenship and Immigration Services. I-864, Affidavit of Support Under Section 213A of the INA You must be at least 18 and living in the United States to qualify as a sponsor.
Your household income must be at least 125% of the federal poverty guidelines for your household size. For 2026, a single petitioner sponsoring one parent (household size of two) needs an annual income of at least $27,050, which is 125% of the $21,640 guideline for a two-person household. Common thresholds in the 48 contiguous states:
- Household of 2: $27,050
- Household of 3: $34,150
- Household of 4: $41,250
- Household of 5: $48,350
You prove income with federal tax returns, W-2s, and recent pay stubs. The most recent tax year carries the most weight, but USCIS looks at the past three years for context.8U.S. Citizenship and Immigration Services. Form I-864 Instructions for Affidavit of Support Under Section 213A of the INA
If Your Income Falls Short
Two ways to close the gap. First, assets. You can supplement income with assets convertible to cash within one year, such as savings, stocks, bonds, or real estate equity. For a parent petition, the net value of those assets must equal at least five times the income shortfall. So if you need $27,050 and earn $22,050, the $5,000 gap requires at least $25,000 in qualifying assets.9Travel.State.Gov. I-864 Affidavit of Support FAQs
Second, a joint sponsor. Someone else can step in and file their own Form I-864, taking on the same legal obligation. A joint sponsor must be a U.S. citizen or lawful permanent resident, at least 18, and living in the United States. Their income (or income plus assets) must independently meet 125% of the poverty guidelines for their own household size plus the immigrant they are sponsoring. This is the common fix for a young petitioner whose income has not caught up to the threshold yet.
After the I-130 Is Approved
The path your parent takes next depends on where they are and how they last entered the United States.
If Your Parent Is Abroad: Consular Processing
The approved petition moves to the National Visa Center (NVC), which collects fees, documents, and the Affidavit of Support.10U.S. Citizenship and Immigration Services. Consular Processing The NVC then schedules an interview at the U.S. Embassy or Consulate in your parent’s home country. Your parent completes a medical exam with a designated physician before the interview. Because parents are immediate relatives, no visa-number wait applies; the only delay is administrative.
If Your Parent Is in the U.S.: Adjustment of Status
If your parent is already inside the country and was lawfully admitted or paroled at their most recent entry, they can generally apply to adjust status without leaving, by filing Form I-485. Because a visa is always available for immediate relatives, the I-485 can be filed at the same time as the I-130 or later. The process includes a medical exam by a USCIS-designated civil surgeon (Form I-693), biometrics, and an interview at a local USCIS field office.11U.S. Citizenship and Immigration Services. Chapter 2 – Eligibility Requirements
A significant advantage for parents of citizens: even if your parent overstayed a visa, they are generally still eligible to adjust status inside the United States, as long as they were inspected and admitted or paroled when they first entered. Most of the bars that would knock out other applicants who fell out of status do not apply to immediate relatives.
The Entry-Without-Inspection Problem
This is where many parent petitions get complicated. To adjust status inside the U.S., your parent must have been “inspected and admitted or inspected and paroled” at their last entry. A parent who crossed the border without going through a port of entry was never inspected and cannot adjust status here, regardless of the immediate relative classification.
In that situation, your parent must leave the country to attend a consular interview abroad. The catch: departing after accumulating unlawful presence triggers re-entry bars. Between 180 days and one year of unlawful presence brings a three-year bar. A year or more brings a ten-year bar. For a parent who has been in the U.S. for years without status, leaving for the interview could mean a decade-long separation.
The Provisional Waiver
Parents of U.S. citizens can apply for a provisional unlawful presence waiver (Form I-601A) before leaving the country. If approved, the waiver neutralizes the three- or ten-year bar so your parent can attend the interview and return without the long wait.12U.S. Citizenship and Immigration Services. Provisional Unlawful Presence Waivers The waiver only takes effect once your parent departs and a consular officer confirms they are otherwise eligible. It does not let your parent adjust status inside the U.S., and it only addresses the unlawful presence ground of inadmissibility.
If your parent has other inadmissibility issues, the provisional waiver will not touch those. A separate Form I-601 may be needed after the consular officer identifies additional grounds. Cases involving criminal history, prior deportation orders, or fraud need careful legal analysis before your parent leaves the country.
Other Reasons a Green Card Can Still Be Denied
Even with an approved I-130 and a provisional waiver, your parent can be denied for other grounds of inadmissibility. The common ones are criminal convictions (especially for dishonesty offenses or controlled substances), prior removal orders, immigration fraud, and certain health conditions. A parent who was previously deported faces a separate five-, ten-, or twenty-year bar depending on the circumstances, and a parent removed after an aggravated felony is permanently inadmissible.
Some grounds have waivers, some do not. The medical exam, required for both consular processing and adjustment, screens for communicable diseases and checks vaccinations. Missing vaccinations count as a ground of inadmissibility, but you cure it by getting the shots.
Work and Travel While the Case Is Pending
If your parent files Form I-485 to adjust status inside the U.S., they can also apply for work authorization by filing Form I-765 under category (c)(9), either together with the I-485 or later after receiving the receipt notice.13USCIS. Form I-765, Instructions for Application for Employment Authorization The Employment Authorization Document allows your parent to work legally while the Green Card decision is pending.
Travel is riskier. If your parent leaves the U.S. while the I-485 is pending without first obtaining advance parole (Form I-131), USCIS will generally treat the adjustment application as abandoned. Even with advance parole, returning is not guaranteed. A customs officer at the port of entry makes a separate call about admission, and any inadmissibility issue that surfaces there can lead to removal proceedings.14U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents, Parole Documents, and Arrival Departure Records The safest choice is no international travel until the Green Card is issued.
What the Whole Thing Costs
The I-130 fee is only the start. A realistic breakdown of government fees:
- Form I-130 (petition): $625 online or $675 by mail
- Form I-485 (adjustment of status): $1,440, which includes biometrics
- Immigration medical exam: typically $150 to $400 for the exam and lab work, plus any missing vaccinations
- Form I-601A (provisional waiver, if needed): varies; check the current USCIS fee schedule
- NVC fees (if consular processing): immigrant visa application fee and affidavit of support fee, collected by the National Visa Center
Government fees alone for adjustment inside the U.S. run roughly $2,200 to $2,500 before any attorney fees. Consular processing costs differ because the State Department charges its own visa application fee instead of the I-485 fee. Hiring an immigration attorney adds several thousand dollars more depending on complexity, and cases involving waivers or inadmissibility issues cost significantly more than clean petitions.
