What is I-751?

USCIS Form I-751 is the petition a conditional permanent resident (CPR) files to convert their 2-year green card to a 10-year permanent green card. Conditional residence applies when the underlying immigrant visa was based on a marriage less than 2 years old at the time the green card was approved. The CPR (and usually the spouse) must file I-751 jointly to remove the conditions; if the marriage ended, the CPR was abused, or removal would cause extreme hardship, the CPR can file a waiver request alone. The basis for the petition (Part 3) is the most consequential field on the form; pick the wrong basis and USCIS denies the petition or returns it for the right basis. File during the 90 days BEFORE the second anniversary of the conditional residence date (the date your CPR card expires).

What happens if you miss the deadline: Late joint-filing without a good reason results in CPR status terminating automatically; the CPR may then be placed in removal proceedings. USCIS may accept a late filing with written explanation showing the delay was for good cause and beyond the petitioner's control. Waiver filers (deceased spouse, divorce, abuse, extreme hardship) are not subject to the 90-day window.

How to file

Filing fee: USCIS April 2024 fees, in effect 2026: $750 paper (biometrics bundled into base fee under the post-04/01/24 rule; no separate $85 line item). Joint filers and most waiver filers pay the standard fee. Battered-spouse / battered-child waivers (1.e / 1.f) and some VAWA-related petitions may be eligible for fee waiver via I-912 on extreme-hardship grounds. Always check uscis.gov/feecalculator before mailing; fees change annually.
Filing method: mail (USCIS lockbox), online (my.uscis.gov)
Filing deadline: Joint filers (basis 1.a / 1.b): must file during the 90-day window BEFORE the second anniversary of conditional residence (the date the CPR card expires). Filing earlier than 90 days before is rejected; filing late is sometimes accepted with a written explanation showing the delay was for good cause and beyond the petitioner's control. Waiver filers (1.c deceased spouse / 1.d good-faith divorce / 1.e battery / 1.f parent's spouse battery / 1.g extreme hardship): can file at any time during conditional residence, including before or after the 90-day window.
How to serve: Not applicable. I-751 is filed directly with USCIS; there is no party to serve.
Wet signature: Yes, sign in pen after printing.
Notarization: No
Original and copies: Original to USCIS lockbox or upload through my.uscis.gov. Keep copies of the entire packet, including the signed petition (joint filers: both spouses signed), copy of CPR card front and back, marriage certificate, proof of bona fide marriage (joint tax returns, joint lease / mortgage, joint bank accounts, joint utility bills, birth certificates of joint children, photos with family, joint life or health insurance, etc.), waiver-specific evidence (divorce decree, death certificate, abuse evidence, hardship documentation), and any tracking number from USPS or courier.

I-912

Request for Fee Waiver

Request for USCIS Fee Waiver. I-751 carries a $750 filing fee plus $85 biometric services fee under the 04/01/24 fee rule (89 FR 6194); I-751 was NOT carved out of fee-waiver eligibility under 8 CFR 106.3(a)(3)(ii), so I-912 applies across all three eligibility bases: (1) means-tested benefit such as Medicaid, SNAP, TANF, SSI, or low-income housing assistance under 8 CFR 106.3(a)(1)(i); (2) household income at or below 150% of the Federal Poverty Guidelines (I-912P) under 8 CFR 106.3(a)(1)(ii); or (3) documented financial hardship (medical bills, unexpected expenses, recent job loss, eviction, etc.) under 8 CFR 106.3(a)(1)(iii). Waiver-basis filers under I-751 item 1.c (conditional resident spouse deceased, no remarriage), 1.d (good-faith divorce, marriage entered in good faith but terminated; 8 CFR 216.5(e)(2)), 1.e (battered spouse, INA 216(c)(4)(C) with VAWA evidence), 1.f (battered child of CPR parent, INA 216(c)(4)(D)), and 1.g (extreme hardship, INA 216(c)(4)(A) with hardship-equivalent-to-deportation showing) commonly qualify on income or hardship grounds because joint household income is no longer available (separation, divorce, or spouse death typically reduces household income below 150% FPG, and post-divorce single-filer status often qualifies for Medicaid / SNAP enrollment that itself triggers basis 1). Joint filers (1.a / 1.b) can also use I-912 when COMBINED household income falls below threshold (large family, dual reduced incomes, recent medical or employment-loss shock). File I-912 with the I-751 packet at the same envelope to USCIS Phoenix Lockbox; USCIS adjudicates the I-912 BEFORE docketing the I-751 substantively (the lockbox holds the packet until fee status is resolved), and a DENIED I-912 sends the I-751 back as 'rejected' (not denied) with the filer given 14 days to refile with the full fee or appeal the I-912 denial; the I-751 priority date is NOT preserved during the rejection-refile cycle, which may matter for the joint-filing 90-day window before CPR expiration. Submit I-912 evidence (benefit award letters, tax transcripts, pay stubs, hardship documentation) at the same time, not later.

I-864

Affidavit of Support Under Section 213A of the INA

Affidavit of Support. The petitioning spouse (or other family-based sponsor) signed I-864 when the CPR adjusted status (or was issued the immigrant visa abroad), creating a contractual support obligation enforceable by the CPR and certain federal / state benefit-granting agencies under INA section 213A and 8 CFR 213a. The I-864 obligation runs from admission as an LPR (CR-1 / CF-1 / IR-1 / K-1 derivative) and survives the conditional-residence period through I-751 conversion to 10-year LPR status. Under 8 CFR 213a.2(e) the I-864 obligation ends only when the CPR or LPR (1) becomes a U.S. citizen via N-400 naturalization, (2) earns 40 quarters of qualifying U.S. work covered by SSA (roughly 10 years, including spousal-credit attribution under 8 CFR 213a.2(e)(2)(i) for marriage quarters), (3) departs the U.S. and abandons LPR status (formal abandonment via I-407 or constructive abandonment after long absence), (4) dies, or (5) is removed from the U.S. via deportation, voluntary departure, or rescission of LPR status. Divorce does NOT terminate the I-864 obligation, so for an I-751 waiver-divorce filer (1.d basis: bona fide marriage that ended in divorce), the now-divorced petitioning spouse's I-864 remains enforceable for past-due support and for restitution of means-tested benefits (SNAP, Medicaid, TANF, SSI, CHIP) the CPR received during conditional residence under INA 213A(b)(1)-(2). CPRs in financial distress after divorce use the I-864 enforcement path in California state court (the contract is enforceable as an ordinary contract under In re Marriage of Kumar (2017) 13 Cal.App.5th 1072 and similar federal decisions) in parallel with the I-751 waiver to maintain income at the 125% Federal Poverty Guideline floor (100% for active-duty military sponsors). The underlying I-864 also continues to count against the ex-spouse's I-130 sponsorship eligibility for any future spouse under INA 213A(f)(1) deeming rules until one of the five termination events occurs, and the ex-spouse must list all prior I-864s on any new I-864 they sign so DOS / USCIS can apply the cumulative income test. CPRs filing the 1.d waiver routinely include copies of the original I-864 and the sponsor's tax / wage history in the I-751 packet, both as bona fides of the original marriage and to preserve the enforcement record against the ex-spouse.

I-90

Application to Replace Permanent Resident Card

Application to Replace Permanent Resident Card. I-90 is the WRONG form for a CPR to convert to 10-year LPR; conditional permanent residents must file I-751 (not I-90) to remove the conditions and obtain the unconditional 10-year card. CPRs filing I-90 thinking it is a renewal will have the I-90 rejected and may miss the I-751 90-day window (joint filers must file in the 90-day window before the CPR card expires under 8 CFR 216.4(a)(1)); failure to timely file I-751 causes automatic termination of CPR status under INA section 216(c)(2)(A) and the case is referred to ICE for removal proceedings (the CPR can argue late filing for good cause and exceptional circumstances under 8 CFR 216.4(a)(6), but late filing is discretionary and not guaranteed; extreme cases may also have a waiver path under 1.d / 1.e / 1.f / 1.g). Waiver-divorce filers (1.d good-faith marriage that ended in divorce), waiver-deceased-spouse filers (1.c), waiver-battered-spouse filers (1.e under VAWA), and extreme-hardship filers (1.g) can file I-751 any time without the 90-day window restriction under 8 CFR 216.5. I-90 only becomes relevant AFTER I-751 approval: replacing a lost / stolen / mutilated 10-year LPR card under I-90 Section A item 2.a (lost / stolen / destroyed), 2.c (never received), or 2.e (mutilated card), or correcting biographic errors under 2.f (incorrect data due to USCIS error other than fee-exempt 2.b), or filing legal-name-change updates under 2.g (post-marriage / divorce / court order). For a CPR whose 2-year card was destroyed during the conditional period, USCIS guidance (USCIS PM 7 Part C Chapter 5) directs filing I-751 (with the I-797 receipt notice extending status by 48 months, plus biometrics support and ADIT stamp at the local field office for proof of LPR status during the conditional-then-pending window) rather than I-90; once I-751 is approved the CPR can then file I-90 if a physical card is still needed beyond the I-797 extension. The I-751 receipt notice itself extends LPR status (under 8 CFR 216.4(a)(2) and the USCIS automatic extension via I-797C class) while I-751 is pending, and as of the 09/04/24 USCIS update the automatic extension is 48 months from the I-797 receipt date, replacing the prior 24-month and earlier 18-month extensions.

N-400

Application for Naturalization (N-400)

Application for Naturalization. Conditional permanent residents (CPRs) whose I-751 is pending or recently approved may file N-400 once the residence clock is met: 3 years under INA section 319(a) and 8 USC 1430(a) if the applicant is still married to and living in marital union with the same U.S. citizen who was the spouse at the time of LPR / CPR grant (the marital 3-year path), or 5 years under INA section 316(a) and 8 USC 1427(a) under the general LPR rule. The CPR clock anchor is the date the I-485 conditional-resident grant was approved (the date stamped on the 2-year CR1 or CF1 card), NOT the I-751 approval date; an applicant who became a CPR on 2023-06-01 can file N-400 under INA 319(a) on 2026-03-01 (90 days before the 3-year mark, under 8 CFR 334.2(b) early-filing carve known as the '90-day rule'). The 3-year clock under 319(a) is independent of removal-of-conditions status: an I-751 pending case extends LPR status by automatic 48-month extension under 8 CFR 216.4(a)(1) and USCIS Policy Manual Vol. 6 Part I Chapter 1, and the CPR remains an LPR for naturalization-clock purposes throughout the extension. Concurrent I-751 + N-400 mechanics. USCIS allows concurrent filing of I-751 and N-400 (the applicant is not required to wait for I-751 approval before filing N-400). Under USCIS Policy Manual Vol. 12 Part G Chapter 2 the N-400 interview can serve as the I-751 interview when both are pending at the same USCIS field office; the same officer reviews both, interviews the CPR (and the joint-petitioner spouse if joint-filed under INA 216(c)(1)(A)), and may approve both at the conclusion of the interview. If the I-751 is denied at the interview, the underlying CPR status terminates and the N-400 is denied as a matter of law (an applicant cannot naturalize without LPR status under INA 318); USCIS then issues an NTA for removal proceedings. If the I-751 is approved, the N-400 may be approved at the same interview (or held briefly for any pending name check or background-check item). Joint vs. waiver path overlay on the 3-year vs. 5-year choice. INA 319(a) requires that the applicant be married to and 'living in marital union with' the same U.S. citizen petitioner for the full 3 years immediately preceding the N-400 filing. (1) JOINT I-751 PATH under INA 216(c)(1) and 8 CFR 216.4: the marriage is intact and both spouses sign the I-751 jointly. Both 3-year 319(a) and 5-year 316(a) N-400 paths are available; 319(a) is faster. (2) GOOD-FAITH-DIVORCE WAIVER under INA 216(c)(4)(B) and 8 CFR 216.5(a)(1)(ii): the marriage was entered in good faith but ended in divorce or annulment before the I-751 was filed. The 319(a) marital 3-year path is unavailable (Marriage ended; no marital union); the 316(a) 5-year general path applies. (3) BATTERED SPOUSE WAIVER under INA 216(c)(4)(C): the marriage was entered in good faith but the CPR was battered or subject to extreme cruelty by the citizen spouse. Same outcome as good-faith-divorce: 5-year general path applies unless the abusive spouse died (then INA 319(a) may apply if the CPR was still 'married to' the citizen at death of citizen under Matter of Hessein, 26 I&N Dec. 374, BIA 2014). (4) EXTREME-HARDSHIP WAIVER under INA 216(c)(4)(A): rare; the CPR shows that removal would cause extreme hardship. 5-year general path applies. (5) DECEASED-SPOUSE WAIVER under INA 204(l) and INA 319(d): under INA 319(d) the surviving spouse of a U.S. citizen serving honorably in the U.S. armed forces who died during active duty as a result of injury or disease incurred in or aggravated by combat can naturalize without any residence or physical-presence requirement; otherwise the 5-year path applies and 319(a) is not available because there is no surviving marital union (but see Matter of Hessein). Continuous residence and physical presence. INA 319(a) and 316(a) impose continuous residence (3 or 5 years respectively) and physical presence requirements: 50 percent of the qualifying period inside the U.S. (18 months of 36 for 319(a); 30 months of 60 for 316(a)) under 8 USC 1427(a)(1) and 1430(a). Absences of more than 6 months are rebuttably presumed to break continuous residence under 8 CFR 316.5(c)(1); absences of more than 1 year (without an approved I-131 re-entry permit) conclusively break it absent INA 316(b) or 317 preservation. Applicants must reside in the same USCIS district or state for at least 3 months before filing (8 CFR 316.2(a)(5); the '3-month state residence rule'). The CPR clock for continuous residence runs from the CPR date (date of LPR / CPR grant), not from the I-751 approval; pending I-751 does not break continuous residence. Good moral character and other bars. INA 316(a)(3) and 8 USC 1427(a)(3) require GMC for the qualifying period plus extension to the oath; bars under INA 101(f) include aggravated felony at any time post-11/29/90 (permanent statutory bar to GMC under INA 101(f)(8)), habitual drunkard, prostitution, smuggling, controlled substance offenses (with single marijuana possession 30g or less carve under INA 101(f) and 212(a)(2)(A)(i)(II)), two-or-more gambling offenses, false testimony, and giving false testimony to obtain immigration benefit (Kungys v. United States, 485 U.S. 759). Failure to register for Selective Service for males age 18 to 26 under 50 USC 3801 et seq. is a GMC bar (USCIS Policy Manual Vol. 12 Part F Chapter 6). Filing N-400 does not cure an unfiled I-751. CPR status terminates on the 2-year-card expiration date if I-751 was not timely filed (joint filers must file in the 90-day window before the 2-year card expires under 8 CFR 216.4(a)(1); waiver filers any time during CPR validity under 8 CFR 216.5(a)(2)), and a terminated CPR cannot naturalize. Late-filing of the joint I-751 is permitted with a showing of exceptional circumstances and good cause under 8 CFR 216.4(a)(6); the late filer who can show good cause keeps CPR status during I-751 pendency and can still file N-400 once the residence clock is met. Filing fees. N-400 fee under 89 FR 6194 (effective 04/01/24) and 8 CFR 106.2(a)(1) is $760 paper / $710 online; $0 fee for INA section 328 / 329 military naturalization (active and recently separated military); $380 reduced fee for income between 150 and 400 percent of federal poverty guidelines under 8 CFR 106.3(b); full I-912 fee waiver available for income at or below 150 percent FPG, means-tested-benefit recipients, and financial-hardship showings under 8 CFR 106.3(a). I-751 fee is $750 plus $85 biometrics under 89 FR 6194 and is bundled into the concurrent filing only if explicitly noted; otherwise pay both fees.

I-130

Petition for Alien Relative

Petition for Alien Relative. I-130 is the originating spouse-based immigrant petition that, when approved within 2 years of the qualifying marriage at the moment the beneficiary obtains LPR status, produces a 2-year conditional green card (CR-1 / CR-2 for consular-processed spouses and children, CF-1 / CF-2 for in-country adjustment under INA 216) and triggers the I-751 obligation. The conditional period runs from the admission as a conditional resident; INA section 216 requires the couple to file I-751 jointly in the 90-day window before the 2-year card expires, calculated backward from the second anniversary of CPR admission per 8 CFR 216.4(a)(1). The I-130 file (Form I-130 itself plus the I-130A spousal supplement, civil documents, joint financial evidence, photos, affidavits) is the underlying administrative record USCIS pulls when adjudicating the I-751 good-faith-marriage analysis under INA 216(c)(1); filers also routinely re-submit copies of the I-130 evidence with I-751 to anchor the bona fides of the original marriage. Filers on the I-751 waiver paths under INA 216(c)(4) (deceased petitioning spouse 1.c, good-faith divorce 1.d, battered spouse 1.e, battered parent 1.f, extreme hardship 1.g) lean even more heavily on the I-130 evidence because the joint signature is unavailable; the good-faith-divorce waiver in particular turns on proof that the marriage at the time of I-130 approval was not fraudulent under INA 204(c), so the I-130-era joint evidence carries forward into the I-751 record. A pending I-130 that has not yet been approved cannot result in CPR status, so there is no I-751 to file until the I-130 approves and the beneficiary takes LPR under it within 2 years of the marriage.

I-485

Application to Register Permanent Residence or Adjust Status

Application to Register Permanent Residence. The U.S.-based AOS pathway that produces conditional permanent residence (CPR) under INA section 216 and 8 USC 1186a when a spouse adjusts status within 2 years of the marriage; I-485 approval in that window issues a 2-year CF-1 (principal) or CF-2 (child) card rather than the standard 10-year card under 8 CFR 216.1. When CPR status attaches. INA 216(a)(1) makes the conditional designation automatic where the alien obtains the status of an alien lawfully admitted for permanent residence on the basis of a marriage that was entered into less than 24 months before the date the alien obtained LPR status. Two parallel routes produce CPR: (1) Consular processing produces CR-1 (spouse) or CR-2 (child) status on visa admission at the port of entry under INA section 211(a) and 8 CFR 235.11; (2) AOS produces CF-1 (spouse, filed in U.S.) or CF-2 (child) on I-485 approval under INA section 245(a). Both routes trip the I-751 obligation. USCIS Policy Manual Vol. 6 Part I Chapter 1 walks the CR vs. CF code distinction; the underlying I-751 obligation is the same. The I-751 90-day filing window. Under 8 CFR 216.4(a)(1) the joint I-751 must be filed in the 90-day window immediately before the second anniversary of the I-485 conditional grant (or, for consular CRs, the second anniversary of admission). The anchor date is the date of LPR admission stamped on the I-485 approval notice (I-797) or on the immigrant visa at port-of-entry admission, NOT the I-751 approval date and NOT the marriage date. Example: I-485 approved 2024-06-01 with CPR card valid until 2026-06-01, I-751 90-day window is 2026-03-03 through 2026-06-01. Late joint filing requires a showing of good cause and extenuating circumstances under 8 CFR 216.4(a)(6) (medical emergency, military deployment, prior counsel error documented). Naturalization clock anchor. The same I-485 admission date is the anchor for the eventual N-400 naturalization eligibility clock: the 5-year continuous-residence clock under INA section 316(a) and 8 USC 1427(a) runs from this admission date; the 3-year continuous-residence clock for U.S. citizen spouses under INA section 319(a) and 8 USC 1430(a) also runs from this same admission date, NOT from I-751 approval. With the 90-day early filing rule under 8 CFR 334.2(b), a CPR who became LPR on 2024-06-01 can file N-400 under INA 319(a) on 2027-03-03 (90 days before the 3-year mark) provided the marriage continues. Pending I-751 does not pause the naturalization clock; USCIS Policy Manual Vol. 12 Part D confirms continuous residence is uninterrupted by I-751 pendency and that 8 CFR 216.4(a)(1) automatic 48-month extension keeps LPR status intact. Fees. I-751 USCIS filing fee under 04/01/24 fee rule at 89 FR 6194 and 8 CFR 106.2(a)(35) is $750 paper / $700 online; biometrics fee $85 (children under 14 included on parent's I-751 do not pay separate biometrics). I-912 fee waiver is available for I-751 under 8 CFR 106.3(a) because I-751 is on the eligible list (the joint-filing scenario, waiver-based scenarios under INA 216(c)(4)(A) extreme hardship / (B) good-faith divorce / (C) battered spouse, deceased spouse under INA 204(l), all qualify for I-912). Children included on a parent's I-751 do not pay separate filing fees under 8 CFR 216.4(c)(3). I-485 grantees who DO NOT file I-751. I-485 grantees whose marriage was 2 years or older at admission, or whose I-485 was filed under non-marriage categories (employment-based EB-1 through EB-5, asylum / refugee adjustment under INA 209(a)/(b), family preference F1 through F4 under INA 203(a), diversity visa under INA 203(c), and Special Immigrant Juvenile / VAWA / U / T-based AOS), receive 10-year LPR cards at I-485 approval and never file I-751. A different removal-of-conditions mechanism applies to EB-5 investor I-829 filers under INA 216A and 8 USC 1186b (2-year investor conditional residence, removed with I-829 in the 90-day window before the 2-year EB-5 card expires). I-829 is NOT addressed by I-751. Consequences of failing to file I-751 in the window. CPR status terminates automatically by operation of law under INA 216(c)(2)(A) and 8 CFR 216.4(a)(6) on the 2-year card expiration date if I-751 was not filed (or properly waivered). USCIS issues an NTA (Notice to Appear in removal proceedings) under 8 CFR 239.1; the terminated CPR is placed in removal under INA 237(a)(1)(D) (failure to maintain conditional status). The terminated CPR may file I-751 in immigration court under 8 CFR 216.5(b) before the immigration judge as a defense against removal; the standard is the same (joint petition with intact marriage, or one of the four waiver paths under INA 216(c)(4)). Late filing outside removal proceedings is accepted with good cause showing under 8 CFR 216.4(a)(6) (USCIS PM Vol. 6 Part I Ch. 3 lists categories of acceptable good cause: serious illness, prior counsel error, lost paperwork, mailing-system delay, immigration officer error).
