Grounds of Inadmissibility and Removal in Adjustment of Status

To get a green card through adjustment of status, you have to prove you are admissible to the United States. That means you don’t fall into any of the categories Congress has defined as disqualifying, evaluated at the moment USCIS reviews your Form I-485. The grounds of inadmissibility for adjustment of status fall into six broad areas: health, criminal history, security concerns, public charge (financial dependence), immigration fraud, and prior unlawful presence or removal.¹ Some can be waived. Others end the case permanently.

Health-Related Grounds

Every adjustment applicant must complete a medical exam with a USCIS-designated civil surgeon, documented on Form I-693. You will be found inadmissible if the exam shows a communicable disease of public health significance, such as active tuberculosis, gonorrhea, or infectious syphilis.¹ The civil surgeon also confirms that you have received required vaccinations, including measles, mumps, rubella, and polio, among others.

A physical or mental disorder counts against you only if it has led, or is likely to lead, to harmful behavior. A diagnosis by itself is not disqualifying. Current drug abuse or addiction, however, is a stand-alone ground for denial.

One procedural detail catches applicants off guard. As of June 2025, your Form I-693 is valid only while the specific application you filed it with is pending. If USCIS denies or you withdraw that application, a future filing requires a fresh exam.²

Most health-related grounds can be waived through Form I-601 if you meet specific familial or humanitarian criteria.

Criminal Grounds

Criminal history is where the most adjustment applications collapse. The statute sweeps in two broad categories: crimes involving moral turpitude and controlled substance violations, plus a separate track for aggravated felonies.³

Crimes Involving Moral Turpitude

A crime involving moral turpitude (CIMT) isn’t a fixed list. It’s a legal concept covering conduct involving fraud, dishonesty, or intent to cause serious harm. Theft, forgery, assault with intent to injure, and many fraud offenses qualify. A single CIMT makes you inadmissible unless you fit the petty offense exception, which requires all three of the following:

You were convicted of, or admitted to, only one CIMT.
The maximum possible sentence for the offense was no more than one year.
You were not sentenced to more than six months, even if part of the sentence was suspended.

That last condition is the one applicants misread. A nine-month sentence with the entire term suspended still counts as a nine-month sentence, which blows the exception.⁴ Separately, two or more convictions of any kind with combined sentences of five years or more create their own independent ground of inadmissibility.¹

Controlled Substance Offenses

Drug offenses are treated more harshly than nearly any other category. A conviction for any controlled substance violation makes you inadmissible. So does a “reason to believe” you were involved in trafficking, a standard notably lower than a conviction.¹

One narrow exception exists: a single offense of simple possession of 30 grams or less of marijuana can potentially be waived. You are still found inadmissible, but you can apply for forgiveness if you can show extreme hardship to a qualifying U.S. citizen or permanent resident relative.¹ Possession above 30 grams, or any distribution involvement, essentially forecloses relief.

Aggravated Felonies

The immigration definition of “aggravated felony” reaches much further than the name suggests. It includes murder, rape, drug trafficking, money laundering over $10,000, theft or burglary with a sentence of at least one year, fraud with losses exceeding $10,000, and many other offenses.⁵ Some are misdemeanors under state law and still count as aggravated felonies for immigration purposes.

The consequences are severe. If you are removed after an aggravated felony conviction, you become permanently inadmissible, and nearly every form of relief disappears. Whether an offense is classified as a CIMT versus an aggravated felony often decides whether an applicant has a realistic path forward.

Security-Related Grounds

Security-based inadmissibility covers terrorism, espionage, sabotage, and involvement with organizations the government considers threats. Participating in terrorist activities, providing material support to designated terrorist groups, or receiving military-style training from such organizations makes you inadmissible, and these grounds generally cannot be waived.¹

Membership in a totalitarian party, including a communist party, is also a ground of inadmissibility. Exceptions apply to involuntary membership, membership that ended more than two years before filing, or membership by someone under 16. Attempts to unlawfully export controlled technology fall in this category as well. USCIS runs your fingerprints and biometrics against federal watchlists and international law enforcement databases as part of the I-485 process.

Public Charge and the Affidavit of Support

You must show you are not likely to become primarily dependent on the government for cash assistance or long-term institutional care. Officers apply a totality-of-the-circumstances test that weighs age, health, family situation, education, skills, and financial resources.⁶ No single factor other than a missing Affidavit of Support automatically results in a public charge denial.

Most family-based applicants must submit Form I-864, in which a sponsor promises to maintain the applicant at 125% of the Federal Poverty Guidelines. This is a legally binding contract between the sponsor and the government.⁷ For 2026 in the 48 contiguous states, the 125% threshold is $27,050 for a household of two and $41,250 for a household of four.⁸ Active-duty military members sponsoring a spouse or child need only meet 100% of the guidelines.

If a sponsor’s income falls short, a joint sponsor can file a separate I-864 to accept the same obligation and fill the gap. Assets can also count, generally at one-third of net value for most applicants and one-fifth for sponsored spouses and children. Failing to submit a sufficient affidavit when one is required is among the most common and most avoidable causes of a public charge denial.

Some categories are exempt from the public charge test entirely: refugees, asylees, T-visa holders, U-visa holders, VAWA self-petitioners, special immigrant juveniles, and applicants adjusting under the Cuban Adjustment Act, NACARA, and several other specialized programs.⁹ Applicants in those categories generally do not need to file an I-864 for adjustment purposes.

Immigration Fraud and False Citizenship Claims

Anyone who willfully misrepresents a material fact, or commits fraud, to obtain an immigration benefit is permanently inadmissible.¹ “Material” means the misrepresentation could have influenced the decision on the benefit. Submitting fraudulent documents, lying at an interview, and similar conduct all qualify. A Form I-601 waiver is available, but only if you can show extreme hardship to a qualifying U.S. citizen or permanent resident spouse or parent.

A false claim to U.S. citizenship is treated more severely still. There is generally no waiver, though Congress has authorized limited exceptions for narrow categories of applicants.¹⁰ It is one of the few grounds where a single act can permanently end your green card chances with essentially no path to forgiveness.

Unlawful Presence Bars

If you accrued more than 180 days but less than one year of unlawful presence in a single stay and then departed the United States, you are barred from returning for three years. If you accrued one year or more and departed or were removed, the bar is ten years.¹¹ These bars are triggered by departure. On their own, they do not block an adjustment application filed by someone who has stayed in the country the entire time. An immediate relative of a U.S. citizen who overstayed but never left is not blocked by the unlawful presence bars for that reason.

The stakes climb sharply if you reenter without inspection after triggering a bar. Reentering after more than one year of total unlawful presence, or after a removal order, creates a permanent bar with no standard waiver. The only route is to leave the United States, remain outside for ten years, and then file Form I-212 asking permission to reapply for admission.¹² Even then, approval is discretionary.¹³

Government entry and exit records are used to check the dates you provide. Discrepancies between the records and your testimony can produce a separate misrepresentation finding on top of the underlying bar.

Which Grounds Can Be Waived

Not every ground is a permanent dead end. Most health-related grounds, many crime-related grounds, unlawful presence bars, and most fraud-based bars can potentially be waived through Form I-601 if you demonstrate extreme hardship to a qualifying relative. “Extreme hardship” is intentionally undefined in the statute. It means hardship beyond the normal disruption that comes with family separation or relocation, evaluated case by case.¹⁴

Some grounds have no waiver, or only extremely narrow relief:

Drug trafficking: no waiver.
Espionage, sabotage, or unlawful efforts to overthrow the U.S. government: no waiver.
Terrorist activity: no waiver.
Participation in Nazi persecution or genocide: no waiver.
False claim to U.S. citizenship: no general waiver, though Congress has created narrow exceptions for limited categories.
Aggravated felony with removal: permanent inadmissibility with only an extremely rare DHS-granted exception.
Permanent bar for illegal reentry: no waiver for ten years, and even then, relief is discretionary.

Confirming whether a waiver exists for your specific ground is the first question to settle before investing time and money in an adjustment application. The I-601 waiver requires its own filing fee, and preparation typically involves substantial documentation of the qualifying relative’s medical, financial, and emotional circumstances.

Discretion: The Last Hurdle

Clearing every inadmissibility ground still doesn’t guarantee approval. Adjustment of status is a discretionary benefit, not an entitlement. The officer weighs positive and negative factors in your record and decides whether approval serves the interest of the United States.¹⁵

Positive factors include family ties in the United States, long residence, steady employment, community involvement, and evidence of good moral character. Negative factors include past immigration violations that do not technically bar you, criminal history that falls below the inadmissibility threshold, and failure to file tax returns. USCIS also weighs country-specific vetting concerns. If the agency cannot adequately screen applicants from a particular country because of limited information, that counts against you.¹⁵

Immediate relatives of U.S. citizens and certain other categories are not subject to the same discretionary analysis. For them, meeting the statutory requirements is enough. For everyone else, a technically clean record with a pattern of minor immigration violations can still lose, while a serious but waivable issue paired with strong equities can win.
