Yes — USCIS can challenge the legality of an already-issued green card even years later, but only within 5 years of the date it was granted through a process called rescission, which can end with a referral to immigration court for deportation.

In short

  • USCIS reopens old green card cases and moves some into removal proceedings, though the phenomenon affects a very small percentage of residents
  • An N-400 denial on grounds of ‘unlawful admission to residency’ now increasingly triggers a Notice to Appear instead of simply closing the case
  • USCIS formally has 5 years to initiate rescission, but in practice notices have surfaced even in older cases
  • More than 99% of permanent residents have no reason for concern — the risk mainly applies to those who spent extended periods living outside the U.S.
  • The outcome depends heavily on the judicial circuit, the judge’s experience, and the quality of how the NTA itself was drafted

Why USCIS reopens old green card cases

USCIS challenges the legality of permanent residency for people who got their green card many years ago, and moves their cases into removal proceedings. This isn’t a mass phenomenon — according to available data, it affects a very small percentage of residents.

What makes this unusual is that some of these notices to appear in court land on people who never even filed for naturalization — meaning there’s no visible trigger coming from the resident themselves. Normally, the most thorough scrutiny from immigration authorities happens specifically at the N-400 stage: the level of review there is significantly higher than when getting a visa or even when the green card itself was issued. That’s why many residents assume that if an issue — say, a crime committed before the green card was granted and never disclosed at the time — didn’t surface during the original background check and fingerprinting, it’s a closed matter. The pattern of reopened old cases shows that this isn’t true: the absence of a question during the first review doesn’t mean USCIS gave up its right to come back to the case later.

Why naturalization (N-400) is riskier than it looks

Filing for naturalization puts an applicant under the most intense scrutiny of their entire immigration journey — far tougher than when they got a visa or even the green card itself (c5, c6). The level of review at the green card stage was historically much lower: some circumstances simply never came to light back then.

Because of this gap in scrutiny, naturalization applications were often denied through the same pattern: USCIS would claim there was a defect in how the green card was issued, meaning the person was never lawfully admitted to permanent residence in the first place (c7, c8). In the past, that kind of denial was the end of the matter — with no further consequences for the applicant (c9).

This is exactly what makes filing N-400 a particularly risky moment: the applicant ends up under heightened review during the exact period when any newly discovered ‘defect’ from the past can surface for the first time (c17, c19).

The scrutiny gap

Review at the green card stage was lighter than at the N-400 stage. USCIS has used that gap to argue admission to residency was unlawful from the start.

How an N-400 denial turns into a Notice to Appear (NTA)

In the past, a naturalization denial on the grounds of ‘never lawfully admitted for permanent residence’ led to nothing further: USCIS denied the N-400, and that was it — no Notice to Appear (NTA) followed. That practice has changed. Now, a denial on this basis comes with a high likelihood of receiving an NTA and ending up in removal proceedings. Observations over the past several months show these cases have become more frequent. If the denial is tied to suspected fraud in obtaining the green card or to a criminal ground, the likelihood of an NTA is high regardless of when exactly the denial arrived.

There is a formal path out — the Nunc Pro Tunc I-601 waiver, which attempts to retroactively fix a defect in the original green card application. But to get this waiver approved, the applicant must prove extreme hardship to a spouse or parent who is a U.S. citizen or permanent resident — not to the applicant themselves. Proving this isn’t always possible, so the waiver shouldn’t be counted on as a guaranteed fix.

A waiver isn’t a guarantee

The Nunc Pro Tunc I-601 waiver requires proving extreme hardship to a citizen or resident spouse or parent — not to the applicant — and approval is far from guaranteed.

How long N-400 processing currently takes

In some USCIS districts, N-400 processing takes 18 months. This matters for anyone considering naturalization specifically because they feel unsafe holding a green card: for all 18 of those months, the applicant remains under the same heightened scrutiny that makes filing N-400 a risky step in the first place.

Banking on risks easing once citizenship is granted isn’t a sure bet either: the current administration, based on its current term, will remain in office for roughly two more years. Subtract the 18-month wait and review period, and what’s left is roughly six months of peace of mind after citizenship is granted. For those six months, an applicant goes through a year and a half of heightened scrutiny — and if the filing is motivated purely by fear over the green card, the outcome may not match the expectation.

The statute of limitations: 5 years for rescission

USCIS has 5 years to initiate rescission — the official procedure to revoke permanent resident status (c29). In practice, though, cases have surfaced that don’t formally fit this window: people who did absolutely nothing after getting their green card — never filed for naturalization, never submitted any applications — unexpectedly received a Notice to Appear in the mail (c27).

One trigger for such a notice: USCIS claiming that the response to a request for evidence filed 5 years earlier, during the green card process, was insufficient, and that the green card should never have been approved at all (c28). Formally, this isn’t rescission proceedings — in these cases USCIS argues the person is in the U.S. without lawful status because the green card approval process itself was conducted incorrectly, meaning the five-year rescission statute of limitations doesn’t apply to this kind of claim.

Who is actually at risk — and who isn’t

More than 99% of permanent residents, based on the available estimate, have no reason for concern (c41, c46). That holds true under two conditions: there was no significant defect in how the green card was obtained, and the resident hasn’t spent too much time outside the United States (c42).

Problems arise for a narrow category of applicants. In practice, there are cases where someone spent nearly a year or more abroad, then returned and lived in the U.S. for another roughly five years (c43). When filing N-400, such an applicant is unexpectedly placed into removal proceedings: authorities argue that years earlier the person effectively abandoned their green card and shouldn’t have been allowed back into the country — in one of the documented cases, the events in question were six years old (c44, c45).

So the real risk group isn’t everyone who got a green card long ago — it’s those whose history includes extended trips outside the U.S. that can be interpreted as abandonment of permanent resident status.

Where the real risk lies

The concern isn’t an old green card itself — it’s extended time spent outside the U.S., roughly a year or more, which can be read as abandonment of resident status.

Why the outcome depends on the judge and the judicial circuit

The legal theory these cases are built on, according to the attorney interviewed, is new and unlikely to survive scrutiny at the federal court level — meaning above the immigration judge and the Board of Immigration Appeals (c30). But how that scrutiny plays out depends on the circuit: the Fifth Circuit tends to give more weight to the findings of the immigration judge and the Board of Immigration Appeals, while the Second and Ninth Circuits more often question these kinds of government decisions (c31, c32). By the same assessment, the current administration is clearly trying to push the boundaries of what’s permissible when it comes to stripping status from lawful permanent residents (c33).

Another variable is the quality of the Notice to Appear itself. Many NTAs are sloppily drafted, look like no one carefully reviewed them, and leave out critical information — some don’t even meet the required regulatory standards (c35, c36). Because of this, attorneys often succeed in getting removal proceedings terminated or most charges dropped — simply because they aren’t backed up by the facts of the case (c37).

The judge’s experience matters too: recently appointed judges more often defer to the Department of Homeland Security’s position without critical scrutiny, while judges with many years on the bench tend to follow established precedent and the law more closely (c38, c39).

The law isn’t the only factor

The outcome depends heavily on the circuit, the judge’s experience, and the quality of the NTA itself — a sloppily drafted NTA often becomes grounds to terminate proceedings.

Frequently asked questions

Can the risk of a case reopening be avoided entirely if the green card was obtained without issues and the person never spent long periods outside the country?

Yes: based on the available estimate, more than 99% of permanent residents have no reason for concern — and this holds true under two conditions at once: there was no significant defect in how the green card was obtained, and the resident hasn’t spent too much time outside the United States.
