Alien Removal Under Section 212 and 237: Grounds, Defenses, and Waivers

Removal under the Immigration and Nationality Act runs on two separate tracks. Section 212 lists the grounds of inadmissibility, which decide whether a non-citizen can enter the United States or adjust to lawful permanent resident status. Section 237 lists the grounds of deportability, which decide whether someone already admitted can be forced to leave. The grounds for removal under INA Sections 212 and 237 overlap in places, but they are not interchangeable: which section applies determines what defenses you have, whether you can be released on bond, and how long you are barred from returning if you lose.

Who Falls Under Section 212 vs. Section 237

Section 212 applies at two moments. The first is when you are physically at a port of entry seeking to be let in. The second is when you file inside the country to adjust status to permanent resident. If any inadmissibility ground applies at either moment, the visa or the green card can be denied unless a waiver is available.¹

Section 237 applies to people who have already been lawfully admitted. Where 212 asks whether the government should let you in, 237 asks whether it should let you stay. You can be placed in removal proceedings under 237 for conduct that occurs after admission, or for having been inadmissible at the time of entry without the government catching it then.²

Grounds of Inadmissibility Under Section 212

Health and Vaccinations

A non-citizen can be found inadmissible for a communicable disease of public health significance, as designated by the Department of Health and Human Services.¹ Immigrants and adjustment applicants must also show proof of required vaccinations set by the CDC.³ Missing vaccinations are not a permanent bar; a civil surgeon or panel physician can administer them during the immigration medical exam.

Criminal History

Certain convictions, and in some cases even admissions of criminal conduct, trigger inadmissibility. The broadest category is a crime involving moral turpitude, which generally covers offenses involving fraud, theft, or intent to harm. A narrow “petty offense” exception applies to a person who committed only one such crime and received a sentence of six months or less. Controlled substance violations also trigger inadmissibility, with no exception for small amounts of marijuana. Prostitution-related convictions and multiple convictions carrying aggregate sentences of five years or more are additional grounds.¹

Public Charge

The government can deny admission to anyone likely to become primarily dependent on government cash assistance for income maintenance. The counted programs are Supplemental Security Income, cash assistance under Temporary Assistance for Needy Families, and state or local cash welfare.⁴ Officers weigh five statutory factors: age, health, family status, financial resources, and education and skills.¹ When an Affidavit of Support (Form I-864) is required, the sponsor must show household income of at least 125% of the federal poverty guidelines. Past receipt of cash benefits alone does not automatically produce a public charge finding; it is one factor.

Fraud and Misrepresentation

Using fraud or willfully misrepresenting a material fact to obtain a visa, admission, or any immigration benefit triggers inadmissibility.¹ This ground is permanent and has no built-in expiration. It covers everything from a fraudulent marriage petition to lying on a visa application about prior criminal history. A waiver on Form I-601 is available only to the spouse, parent, or child of a U.S. citizen or lawful permanent resident, and the applicant must show extreme hardship to that qualifying relative.

Security-Related Grounds

People suspected of espionage, terrorist activity, or involvement in totalitarian parties are inadmissible on security grounds. These are among the hardest to overcome because most cannot be waived, and the government can rely on reasonable suspicion rather than a criminal conviction.

Unlawful Presence and Prior Removals: The Time Bars

Some of the harshest inadmissibility grounds are automatic time bars, and they catch people off guard because they trigger the moment the underlying event occurs.

If you accumulate more than 180 days but less than one year of unlawful presence in a single stay and then leave, you are barred from returning for three years. If your unlawful presence reaches one year or more and you then depart or are removed, the bar becomes ten years.⁵ These bars apply even if an approved visa petition is waiting for you.

Separate bars apply to a prior removal order. Someone removed on arrival is inadmissible for five years if they try to return. Removal after full proceedings brings a ten-year bar. A second or subsequent removal extends it to twenty years. Removal based on an aggravated felony conviction is a permanent bar.¹ Form I-212 can sometimes overcome these bars by requesting permission to reapply for admission, but approval is discretionary.

Grounds of Deportability Under Section 237

Inadmissible at the Time of Entry

If a non-citizen was technically inadmissible when they entered but the issue was missed, they become deportable whenever the government discovers it. A common example: someone enters on a valid visa with an undisclosed criminal conviction that would have barred entry, and years later a background check during a green card application surfaces the conviction.

Criminal Offenses After Admission

Criminal convictions are the leading trigger for deportability. The categories include crimes involving moral turpitude, aggravated felonies, controlled substance offenses, firearms offenses, and domestic violence crimes.² An aggravated felony conviction after admission makes a person deportable and eliminates most forms of relief.

Status Violations

Violating the conditions of your visa is itself a deportability ground, with no criminal conduct required. A student who drops below a full course load, a temporary worker who leaves the sponsoring employer, and a visitor who overstays can all be placed in proceedings.

Security-Related Grounds

Espionage, terrorist activity, and other national-security threats after admission make a non-citizen deportable. As with the 212 counterpart, waivers are extremely limited.

How Criminal Convictions Trigger Removal

Criminal history is the single most common reason people end up in removal proceedings, and the immigration consequences of a plea often surprise both the defendant and the criminal defense attorney. The INA uses its own definitions, which do not always match state law classifications.

Crimes Involving Moral Turpitude (CIMT)

The INA does not define CIMT, but courts have generally read it to cover offenses involving fraud, larceny, intent to cause serious bodily harm, and similar conduct reflecting dishonesty or disregard for others’ rights. Common examples include theft, forgery, assault with intent to harm, and spousal abuse.

Under Section 212, a single CIMT can block entry unless the petty offense exception applies. Under Section 237, a single CIMT triggers removal only if two conditions are met: the crime was committed within five years of admission, and the offense carries a potential sentence of one year or more.² Two or more CIMT convictions after admission make a person deportable regardless of timing or sentence length, as long as they did not arise from a single scheme of criminal misconduct.

Aggravated Felonies

“Aggravated felony” is defined in the INA and covers over 20 offense categories. Despite the label, a crime does not need to be a felony under state law to qualify; some misdemeanors with a sentence of one year or more fit the definition.⁶ The list includes murder, sexual abuse of a minor, drug trafficking, firearms trafficking, theft offenses with a one-year sentence, and crimes of violence with a one-year sentence, among others.

An aggravated felony conviction is the most damaging criminal ground. It makes a person deportable at any time after admission, bars asylum, cancellation of removal, and voluntary departure, and triggers a permanent bar to re-entry after removal.² Cases are often won or lost at the criminal defense stage, where a plea structured to avoid an aggravated felony classification can preserve every option that a plea in the wrong shape would destroy.

Controlled Substance Offenses

A conviction for any offense relating to a controlled substance at any time after admission makes a person deportable.² The single exception on the deportability side is one offense of simple possession of 30 grams or less of marijuana for personal use. It does not cover distribution, possession with intent to distribute, or possession of any other controlled substance regardless of amount. It also does not help on the inadmissibility side, where no marijuana exception exists.

Mandatory Detention Without Bond

Not everyone in removal proceedings can post bond and wait for a hearing at home. Federal law requires the government to detain certain non-citizens without the possibility of bond. The mandatory categories include people inadmissible on criminal grounds, deportable for an aggravated felony or a CIMT with a sentence of at least one year, deportable for controlled substance or firearms offenses, and those subject to security-related grounds.⁷ The only statutory release from mandatory detention runs through a narrow witness-protection provision that rarely applies in practice.

For non-citizens who are not subject to mandatory detention, an immigration judge can set a bond. The statutory minimum is $1,500, and bond is denied if the judge finds the person a flight risk or a danger to the community.

How Removal Proceedings Work

Proceedings begin when the Department of Homeland Security serves a Notice to Appear. The NTA must state the charges, the legal basis for them, and the conduct alleged to make the person removable.⁸ Once served, you have five days to file a current address and phone number with the immigration court. Failing to keep that address current is one of the fastest ways to lose, because the judge can order removal in your absence if notices go to an outdated address.

Cases are heard by immigration judges within the Executive Office for Immigration Review, a division of the Department of Justice. The first hearing is a master calendar hearing: the judge confirms identity, reads the charges, and asks whether you admit or deny the allegations. If you plan to apply for relief, you indicate it there, and the judge schedules an individual hearing where you testify, present evidence, call witnesses, and make legal arguments. You have the right to counsel, but the government does not provide one.

Appealing to the Board of Immigration Appeals

If the immigration judge orders removal, you can appeal to the Board of Immigration Appeals by filing Form EOIR-26. As of March 9, 2026, the appeal deadline is 10 calendar days from the date of the judge’s decision, down sharply from the prior 30-day window.⁹ Missing the deadline generally forfeits the right to appeal. If the deadline falls on a weekend or federal holiday, it extends to the next business day. Asylum cases where the application was not denied on certain procedural grounds still have a 30-day window.

Defenses and Relief From Removal

Being charged as removable does not always mean deportation. Several forms of relief exist, but each has strict eligibility rules that depend on your status, time in the country, criminal history, and the nature of the removal charge.

Cancellation of Removal for Permanent Residents

If you are a lawful permanent resident, the judge can cancel removal if you have held your green card for at least five years, have lived in the United States continuously for at least seven years since being admitted in any status, and have not been convicted of an aggravated felony.¹⁰ Cancellation is discretionary, so meeting the three criteria only makes you eligible. The aggravated felony bar is absolute.

Cancellation of Removal for Non-Permanent Residents

Non-citizens without green cards face a harder standard. You must show at least ten years of continuous physical presence, good moral character throughout that period, no disqualifying criminal convictions, and that your removal would cause “exceptional and extremely unusual hardship” to a U.S. citizen or permanent resident spouse, parent, or child.¹⁰ That hardship standard is intentionally high and goes well beyond normal family separation. The ten-year clock stops the moment the NTA is served, so the full decade must have run before DHS initiates proceedings.

Asylum, Withholding, and CAT Protection

Asylum protects people who face persecution in their home country on account of race, religion, nationality, membership in a particular social group, or political opinion. The application must be filed within one year of arrival in the United States.¹¹ Exceptions exist for changed country conditions or extraordinary circumstances, but the one-year bar defeats more asylum claims than any substantive issue.

Withholding of removal uses the same five protected grounds but requires a higher burden: that persecution is “more likely than not” if you are returned. Withholding has no one-year filing deadline and is not barred by an aggravated felony conviction (asylum is). The trade-off is that withholding does not lead to a green card; it only blocks removal to the specific country where you face persecution.

Protection under the Convention Against Torture is available to anyone who can show it is more likely than not they would be tortured by, or with the acquiescence of, a government official if removed. CAT has no criminal bars at all, which makes it the last line of defense for people with aggravated felony convictions.

Adjustment of Status During Proceedings

If you have an approved immigrant visa petition and a visa is immediately available, you may be able to adjust status to permanent resident even while in proceedings. You must show you were inspected and admitted or paroled, that you are admissible, and that you merit a favorable exercise of discretion.¹² The Form I-485 is filed with the immigration court, with a copy to USCIS. This path only works if you already have a qualifying family or employment relationship supporting an immigrant petition.

Voluntary Departure

Voluntary departure lets you leave on your own instead of being formally removed, and it avoids the re-entry bars that follow a removal order. Granted before the conclusion of proceedings, it can allow up to 120 days to arrange departure. Granted by the judge at the end of proceedings, it allows up to 60 days.¹³ The judge may require a bond and surrender of your passport. Failing to leave by the deadline converts voluntary departure into a removal order and adds penalties, so only accept it if you are genuinely prepared to go.

Waivers of Inadmissibility

When a 212 ground applies, a waiver can sometimes forgive it. Waivers are not available for every ground; security and terrorism-related grounds generally cannot be waived.⁴ For grounds that can be waived, the usual requirement is proving that denying admission would cause “extreme hardship” to a qualifying U.S. citizen or permanent resident relative, typically a spouse or parent.

Extreme hardship means something well beyond the normal difficulties of family separation. The applicant must show, through detailed evidence, the specific impact absence would have on the qualifying relative’s health, finances, education, and emotional well-being.¹⁴ General statements about missing a family member are not enough. Strong applications include medical records, financial documents, therapy records, country conditions evidence, and declarations explaining the concrete consequences of separation.

The primary waiver form is Form I-601.¹⁵ To overcome a prior removal order or a bar triggered by unlawful re-entry, Form I-212 is required instead or in addition. The applicant carries the burden by a preponderance of the evidence, and the final decision is discretionary: the officer balances positive factors (family ties, community involvement, rehabilitation) against negative ones (seriousness of the offense, recency of the violation).¹⁶
