I-751 Filing Window Calculator: When Can You File to Remove Conditions on Your Green Card?

If you are filing Form I-751 together with your spouse, USCIS says you must file it "during the 90-day period immediately before your conditional residence expires." A conditional green card expires two years after the Resident Since date printed on it, so the window opens 90 days before that second anniversary. A joint petition that arrives earlier may be rejected. If you are asking USCIS to waive the joint filing requirement, there is no 90-day window to wait for.

• Filing jointly, your window is the 90 days before the card expires, and the card expires two years after the Resident Since date.
• USCIS may reject a joint petition that arrives before the window opens and send it back.
• If you are filing with a waiver (after a divorce, a spouse's death, abuse, or on extreme hardship), you do not wait for the window.
• If you missed the window, you can still file late with a written explanation of why.

Rules read: November 10, 2026, from the USCIS Form I-751 page, the Form I-751 instructions (edition 04/01/24), USCIS's When to File Your Petition to Remove Conditions page and the fee schedule, Form G-1055 (edition 10/26/26). Every rule below links to the page it came from. When USCIS changes one, this page is re-read and the date changes.

What this does and what it does not. The calculator does date arithmetic on the rules USCIS publishes. It cannot judge your evidence or your record. It runs in your browser, needs no signup, and nothing you type leaves your device. The government fee is also in our USCIS fee calculator.

When can I file Form I-751?

Enter the Resident Since date from your two-year green card. The calculator returns the day your 90-day window opens, the day the card expires and where today falls. If you would rather use the Card Expires date printed on the card, switch the first option.

How the 90-day window works

Three USCIS pages set the rule. The I-751 instructions say that if you file jointly with your spouse, "you must file it during the 90-day period immediately before your conditional residence expires." USCIS's Removing Conditions on Permanent Residence Based on Marriage page says the conditional green card "will expire 2 years from the date you obtain conditional permanent residence." The Form I-751 page warns that a petition filed before the first day of the window "may be rejected."

The calculator does two steps. The card expires on the second anniversary of the Resident Since date, and the window opens 90 calendar days before that. USCIS publishes its own Filing Date Calculator on its When to File page. It asks for the Card Expires date instead and gives one example: a card that expires June 30, 2023 has an earliest filing date of April 1, 2023. Our calculator returns the same date for that card. USCIS's wording is that you file "before" the conditional residence expires, so the table shows the day before the expiration date as the last day inside the window.

February 29. If your Resident Since date is February 29, the second anniversary falls in a year with no February 29. USCIS does not address that case on the pages we read, so the calculator takes the cautious reading at both ends: it opens the window 90 days before March 1 and treats February 28 as the day the card expires. The Card Expires date on your card settles it. If the card shows a date, choose Card Expires in the calculator and enter it.

Children. The instructions say you can include your children on your petition if they got conditional residence on the same day as you or within 90 days after. Children who got it later, or whose conditional resident parent has died, file their own I-751. A child who was not included on a parent's petition and files a separate joint petition with a stepparent may file at any time before conditional status expires, according to the Form I-751 page.

Joint filing vs waiver

If you are still married to the spouse through whom you got conditional residence, the I-751 instructions tell you to file jointly with that spouse, inside the 90-day window. You can file without your spouse, by asking USCIS to waive the joint filing requirement, if one of these applies:

• You entered the marriage in good faith, but your spouse later died.
• You entered the marriage in good faith, but it ended in divorce or annulment.
• You entered the marriage in good faith, but your spouse battered you or subjected you to extreme cruelty.
• Your conditional resident parent entered the marriage in good faith, but you were battered or subjected to extreme cruelty by that parent or by the parent's U.S. citizen or permanent resident spouse.
• Ending your status and removing you from the United States would cause extreme hardship.

A waiver petition does not wait for the window. The Form I-751 page says you may file it "at any time before your conditional permanent resident status expires." The instructions go further: any time after you get conditional residence "and before you are removed from the United States." The Removing Conditions page says a waiver can be requested before or after the 90-day period, "until a final removal order has been issued," and that you may ask USCIS to consider more than one waiver ground. If the waiver is based on divorce or annulment, the When to File page says the proceedings must be completed before you file. If you filed while a divorce was still pending, USCIS will send a request for evidence asking for the final decree.

The fee is the same either way, with one exception. Form G-1055 (edition 10/26/26) lists $750 to file on paper and $700 to file online. There is no fee ($0) for a conditional resident, spouse or child who files a waiver based on battery or extreme cruelty, and some filers can ask for a fee waiver on Form I-912.

A waiver case rests on evidence of the marriage and of how it ended or why you cannot file together, and it is decided case by case. If that is your situation, request a consultation before you file.

What happens if you miss the window

The I-751 instructions say that if the petition is not filed, "you will automatically lose your permanent resident status two years from the date on which you were granted conditional status," and you become removable. The Removing Conditions page says USCIS will send a notice that you failed to remove the conditions and will start removal proceedings with a Notice to Appear. At the hearing, you have to prove you met the requirements of your conditional status.

You can still file late. The instructions say that if your failure to file was "through no fault of your own," you may file with a written explanation and ask USCIS to excuse the delay. USCIS can excuse it if you show, when you file, "that the delay was due to extraordinary circumstances beyond your control and that the length of the delay was reasonable." The When to File page asks for a request to excuse the late filing and a written explanation showing good cause and extenuating circumstances. USCIS decides whether the reason is good enough.

Talk to a lawyer before you file if your card has already expired, if you have received a Notice to Appear, if your marriage has ended or is ending, if there was abuse, or if you have any arrest or charge on your record. If you are already in removal proceedings, our deportation defense page explains how we handle cases at the Orlando Immigration Court.

What to send

This is a summary of the evidence categories in the I-751 instructions and the checklist on the Form I-751 page. Read the instructions themselves before you file.

• Your card. Copies of the front and back of your Permanent Resident Card, and of the cards of any conditional resident children on your petition.
• Evidence the marriage was real. Documents showing you married in good faith, covering the relationship from the wedding to now (or to when it ended). The instructions give examples: birth certificates of children born during the marriage, a lease or mortgage showing you live together, joint bank accounts, joint tax returns, insurance naming the other spouse, joint utility bills or loans, and sworn affidavits from at least two people who have known you both since you got conditional residence. Affidavits have to be backed by other evidence.
• For a waiver. A death certificate, a final divorce or annulment decree, evidence of abuse (police, court, medical or shelter records and similar), or evidence of extreme hardship, depending on the ground. Hardship evidence must relate to things that arose during your two years of conditional residence.
• Criminal history. If you were ever arrested, detained or charged, the official records or court dispositions the instructions list.
• Late filing. If you file after the card expires, the written explanation described above.
• Translations and signatures. A full certified English translation of any foreign-language document. USCIS rejects an unsigned petition.

Once a properly filed I-751 is accepted, the Removing Conditions page says the receipt notice extends your conditional status and work authorization for 48 months. For how the marriage case got started, see our marriage green card page. If you plan to apply for citizenship later, our N-400 date calculator explains why conditional residents usually need an approved I-751 first.

Frequently asked questions

Can I file the I-751 before the 90-day window opens?

Not if you are filing jointly. The When to File page says a joint petition USCIS receives before the window opens "may be rejected and returned to you for filing too early." Waiver petitions and separate joint petitions filed by a child with a stepparent are not held to the window.

Can I file the I-751 after my card expires?

Yes, but you must include a written explanation and ask USCIS to excuse the late filing. Under the instructions, USCIS can excuse it if the delay came from extraordinary circumstances beyond your control and lasted a reasonable time. Until then, your conditional status has ended, and USCIS can start removal proceedings.

When do I file the I-751 after a divorce?

After a divorce you file on your own with a waiver, and the 90-day window does not apply. The When to File page says the divorce or annulment must be final before you file. Include the final decree and evidence that you entered the marriage in good faith.

How long does the I-751 receipt notice extend my green card?

48 months past the card's expiration date, according to the Removing Conditions page, for a petition that is properly filed. If the I-751 is still pending after that and you need proof of status, USCIS says to call its Contact Center at 800-375-5283.

Methodology and reuse

On November 10, 2026 we read the USCIS Form I-751 page (last reviewed June 16, 2026), the Form I-751 instructions (edition 04/01/24), the When to File Your Petition to Remove Conditions page with its Filing Date Calculator (last reviewed September 14, 2023), the Removing Conditions on Permanent Residence Based on Marriage page (last reviewed December 12, 2023) and Form G-1055 (edition 10/26/26). The card's expiration date is the Resident Since date plus two years, and the window opens 90 calendar days before it, the same count USCIS's calculator uses. We checked the arithmetic against USCIS's own example (Card Expires June 30, 2023, earliest filing date April 1, 2023). The one judgment call is the February 29 Resident Since date, described above. Nothing is estimated. When USCIS changes a rule, the form edition or the fee, the page is re-read and the date at the top changes.
