A green card holder who files today to sponsor an unmarried adult child should plan on a wait of about nine years before that child can immigrate, and considerably longer if the child was born in Mexico or the Philippines. The category that applies, F2B, has one of the deepest backlogs in family-based immigration. So the honest answer to how long it takes for a green card holder to sponsor an adult child is: file the petition now, and expect most of a decade or more before a visa becomes available.
Current F2B Wait Times by Country
The Department of State’s March 2026 Visa Bulletin puts the F2B Final Action Date for most countries at December 1, 2016. That means visas are being issued now to people whose petitions were filed over nine years ago.1U.S. Department of State. Visa Bulletin for March 2026 The picture is worse for oversubscribed countries:
- Most countries: about 9 years (Final Action Date of December 2016)
- Philippines: about 13 years (Final Action Date of December 2012)
- Mexico: about 17 years (Final Action Date of February 2009)
These numbers move month to month. The bulletin sometimes jumps ahead when visa numbers free up, and sometimes stalls when demand outstrips supply. A petition filed today will not necessarily face exactly the wait current applicants are seeing, but the F2B backlog has been deep for many years and shows no sign of clearing.
The child’s country of chargeability is set by their country of birth, not their citizenship or where they currently live.2U.S. Department of State Foreign Affairs Manual. 9 FAM 503.1 – Numerical Limitations Overview A person born in Mexico who now lives in Canada still faces the Mexico backlog. In narrow circumstances, a beneficiary can be charged to a spouse’s country of birth if it has a shorter wait.
Why the Wait Is This Long
Federal law caps the total number of immigrant visas issued to natives of any single country at 7% of the annual family-sponsored and employment-based total.3Office of the Law Revision Counsel. 8 USC 1152 – Numerical Limitations on Individual Foreign States High-demand countries like Mexico and the Philippines hit that ceiling every year, and the excess demand does not carry forward in any meaningful way. The backlog compounds. India and China are also subject to the per-country cap, but F2B demand from those countries currently tracks the “all other countries” line.1U.S. Department of State. Visa Bulletin for March 2026
Who Can Actually Be Sponsored
A lawful permanent resident can petition for an unmarried son or daughter who is 21 or older.4U.S. Citizenship and Immigration Services. Family of Green Card Holders (Permanent Residents) That is the F2B preference category.5U.S. Citizenship and Immigration Services. Green Card for Family Preference Immigrants Two conditions matter: the child must be unmarried, and they must be at least 21. If either changes, the case changes.
The immigration definition of “child” covers children born in wedlock, stepchildren (only if the marriage that created the step-relationship happened before the child turned 18), legitimated children, children born outside of marriage, and children adopted before age 16 who lived with the adoptive parents for at least two years.6Office of the Law Revision Counsel. 8 USC 1101 – Definitions The stepchild age cutoff catches people off guard. A marriage that took place after the child’s 18th birthday does not create a qualifying step-relationship, no matter how close the family bond.
A boundary worth stating plainly: a green card holder cannot sponsor a married adult child at all. The category for married adult children (F3) is reserved for the children of U.S. citizens.
File the I-130 Now, Because the Priority Date Is Everything
The process starts with Form I-130, Petition for Alien Relative, filed with USCIS.7U.S. Citizenship and Immigration Services. I-130, Petition for Alien Relative The form establishes the qualifying family relationship, and you submit it with proof of your permanent resident status, evidence of the parent-child relationship (typically a birth certificate), and biographical information for both of you.
The date USCIS properly receives the I-130 becomes the priority date. That date locks in your child’s place in the queue. With F2B waits stretching across a decade or more, every month of delay in filing adds roughly a month to the back end of the wait. There is no reward for waiting to file until circumstances are more settled; the smarter move is to file as soon as the relationship qualifies and let the years of backlog run while the family gets on with life.
After USCIS approves the petition, the case waits. Nothing further happens until the priority date becomes current on the monthly Visa Bulletin.8U.S. Citizenship and Immigration Services. Visa Availability and Priority Dates Until it does, the sponsor’s main job is to keep the address on file current and hold on to the approval notice.
Events During the Wait That Change the Timeline
Nine to seventeen years is long enough that circumstances shift. Some changes destroy the case, one creates a decision worth thinking through carefully, and one silently ruins the beneficiary’s options in the U.S.
If the Child Marries, the Petition Is Gone
If the unmarried adult child marries while the F2B petition is pending, the petition is automatically revoked.9eCFR. 8 CFR 205.1 – Automatic Revocation There is no waiver. The priority date, the years of waiting, and the filing fee are all lost. This is one of the most common ways F2B cases fail.
If the Sponsor Naturalizes, the Case Converts
If you become a U.S. citizen while your child’s F2B petition is pending, the petition automatically converts to F1 (unmarried adult children of U.S. citizens), and the original priority date is preserved.10U.S. Citizenship and Immigration Services. USCIS Policy Manual – General Eligibility Requirements Whether that helps or hurts depends on the current Visa Bulletin. F1 sometimes moves faster than F2B, and sometimes slower. Before filing for naturalization, compare the Final Action Dates in both categories.
If F2B is currently moving faster, you can opt out of the automatic conversion by sending a written request to USCIS, keeping the petition in F2B as though you were still a permanent resident.10U.S. Citizenship and Immigration Services. USCIS Policy Manual – General Eligibility Requirements
One related point. If you naturalize and your child later marries, the case converts to F3 rather than being revoked outright. F3 waits are longer than F2B, but that is still better than losing the petition.
Unlawful Presence Creates a Trap
Some beneficiaries are already in the U.S. and fall out of status during the wait. More than 180 days of unlawful presence followed by a departure triggers a three-year bar on reentry; more than a year triggers a ten-year bar.11U.S. Citizenship and Immigration Services. Unlawful Presence and Inadmissibility F2B beneficiaries generally cannot adjust status in the U.S. if they are unlawfully present when they file.12U.S. Citizenship and Immigration Services. USCIS Policy Manual – Unlawful Immigration Status at Time of Filing But leaving to pursue consular processing triggers the reentry bar. Anyone in this situation should get legal counsel before either filing or departing.
What It Costs Across the Years
Government fees stack up across a decade. The main ones:
- Form I-130 petition fee, set by USCIS and periodically adjusted; the current amount appears on the USCIS fee schedule (Form G-1055). Online filing is slightly cheaper than paper.
- National Visa Center immigrant visa processing fee: $325 for family preference cases.13U.S. Department of State. Fees for Visa Services
- Form I-485 filing fee if the child is in the U.S. and eligible to adjust status, plus separate fees for Form I-765 (work permit) and Form I-131 (advance parole) if filed.
- Medical examination, typically $150 to $400 and paid directly to the physician.
- Certified English translations of foreign-language documents, typically $25 to $40 per page.
The Affidavit of Support (Form I-864) has no filing fee but is a binding financial commitment that lasts until the sponsored person naturalizes, earns 40 qualifying quarters of Social Security work credits, permanently leaves the country, or dies.14U.S. Citizenship and Immigration Services. Affidavit of Support Government fees alone run well over $1,000 before translation, medical, and any travel to a consulate.
Keeping the Case Alive Through the Wait
File Form AR-11 whenever you move so USCIS notices reach you; a missed notice at the wrong moment can be treated as an abandoned petition. Renew your green card before it expires. If your child’s marital status, address, or immigration status changes, disclose it promptly rather than hoping it goes unnoticed. Delayed disclosure is handled far more harshly than a proactive update, and mismatched documents are the leading cause of Requests for Evidence that stall a case by months at each stage.
