A conditional Green Card is valid for two years, and USCIS says the petition to remove the conditions must be filed within the 90 days before the card expires. This calculator turns the expiration date printed on the card into the dates of that window. It uses the rule on the USCIS page on conditional permanent residence and nothing else.
Quick answer
| Item | USCIS rule |
|---|---|
| Card validity | Two years |
| Marriage-based cases | Form I-751, Petition to Remove the Conditions of Residence |
| Entrepreneur cases | Form I-829, Petition by Entrepreneur to Remove Conditions |
| When to file | Within the 90 days before the conditional card expires |
| If conditions are not removed | Permanent resident status is lost and the person becomes removable |
How to use the calculator
- Find the expiration date printed on the conditional Green Card.
- Enter it in the date field. The browser’s date picker accepts the date in the format it shows.
- Read the three dates in the result: when the window opens, when it ends, and how many days remain from today.
- Compare the result with the USCIS page on conditional permanent residence, which also offers a Filing Calculator, before filing.
How the result is calculated
The window start is the card expiration date minus 90 days. The window end is the expiration date itself, because the rule asks for filing within the 90 days before the card expires. The current date is read from the device. Nothing is sent anywhere.
What USCIS says about conditional residence
The page states that a conditional permanent resident receives a Green Card valid for two years and that the card cannot be renewed. It names two groups that must remove conditions: marriage-based cases and entrepreneur, or investor, cases. A person who does not remove the conditions loses permanent resident status. The USCIS page on maintaining permanent residence adds that USCIS can also terminate conditional status for reasons such as fraud.
Which form applies
Marriage-based cases use Form I-751. Entrepreneur cases use Form I-829. The calculator gives the same window for both, because the page gives the same 90-day rule for removing conditions. A person who is not sure which category the card falls under should check the documents USCIS issued or ask USCIS or a licensed attorney.
How this differs from replacing a card
A standard Green Card is replaced with Form I-90 when it is expired or will expire within six months. A conditional card cannot be handled that way. The window calculator for standard cards is the Green Card renewal window calculator, and the long version of the rule is in Green Card expiration and renewal.
Common mistakes
- Counting from the date the card was issued instead of the expiration date.
- Assuming a conditional card can be renewed like a standard card.
- Filing before the window opens.
- Using the date of the receipt notice or an old card.
- Treating the result as a decision about a case. It only shows the dates in the rule.
Limits of the calculator
The tool does not know the facts of a case. It does not cover waivers or what happens after a petition is filed. Questions about those points belong with USCIS or a licensed immigration attorney.
Early and late filing
The USCIS page for Form I-751 says a joint petition is filed during the 90 days immediately before the conditional residence ends and that filing earlier may lead to the petition being rejected. It tells a person who files late to include an explanation for the delay but does not state a standard. The USCIS page for Form I-829 says that if the 90-day window is missed, conditional status ends and the person becomes removable, and that a late petition may be excused for good cause and extenuating circumstances, at USCIS discretion, with a written explanation. Waiver and certain other I-751 filings may be made at any time before the card expires, according to the I-751 page.
Frequently asked questions
When does the 90-day window start?
Ninety days before the expiration date printed on the conditional card.
Can the petition be filed earlier?
USCIS says to file within the 90 days before the card expires. The calculator therefore treats earlier dates as outside the window.
Is the window the same for Form I-751 and Form I-829?
The USCIS page gives one 90-day rule for removing conditions in both marriage-based and entrepreneur cases.
What if the card has already expired?
The calculator says so. USCIS states that status is lost when conditions are not removed, so the case should go to USCIS or an attorney.
