A U.S. Job Posting Usually Cannot Exclude U.S. Citizens

For a job in the United States, usually not. A posting that says “U.S. citizens not eligible,” “H-1B only” or “temporary visa holders preferred” can violate federal law by discriminating against protected workers based on citizenship, immigration status or national origin.

The reverse question has a related answer: an employer also generally should not advertise a position as “U.S. citizens only” unless a law, regulation, executive order or government contract requires that restriction.

What federal law covers

The Immigration and Nationality Act (INA) generally prohibits employers with four or more employees from discriminating in hiring, firing, recruitment or paid referral because of citizenship status. Protected people include U.S. citizens, U.S. nationals, recent lawful permanent residents, refugees and people granted asylum. Coverage for some permanent residents and other noncitizens is more limited, so individual status can matter. The Justice Department’s Immigrant and Employee Rights Section (IER) explains the protected groups and employer-size threshold.

That protection applies when an employer prefers temporary-visa workers over U.S. citizens as well as when it improperly excludes noncitizens. A visa program does not by itself authorize citizenship-status discrimination in recruitment.

A posting may also raise a national-origin discrimination issue. Title VII protects Americans as well as people from other national origins, and the EEOC says discriminatory advertising can include “H-1B preferred” and “H-1B only.” It also identifies application processes made harder for U.S. workers than for visa holders as possible disparate treatment. The EEOC explains these examples; Title VII generally covers employers with at least 15 employees, while state or local laws may cover smaller organizations or provide broader protection.

Read the exact restriction

Posting language	What it usually means
“H-1B only,” “OPT preferred” or “U.S. citizens not eligible”	A serious discrimination warning sign because the employer appears to be selecting by citizenship or immigration status.
“Must be authorized to work in the United States”	Generally asks whether the candidate may legally work, not whether the candidate has a particular citizenship.
“We do not provide employment-visa sponsorship”	Generally addresses whether the employer will sponsor a visa. DOJ guidance says employers may ask whether applicants have the legal right to work and whether they will need sponsorship. The answer should not be used as a proxy for an unrelated citizenship preference.
“U.S. citizenship required by [identified law or contract]”	Potentially lawful, but HR should verify that the cited requirement applies to this specific position.
“Must be a U.S. person under export-control rules”	Not the same as “U.S. citizen.” For the relevant export-control rules, U.S. persons can include citizens, nationals, lawful permanent residents, refugees and asylees.

The exceptions are narrow

The INA permits a citizenship restriction when it is required by a law, regulation, executive order or federal, state or local government contract. The regulations also recognize an Attorney General determination that a restriction is essential for doing business with a government agency. These exceptions turn on an actual requirement—not a customer preference, recruiting convenience or unsupported assumption about compliance. The current federal regulation lists the exceptions.

A position requiring access to classified information can be one example. The State Department says a person generally must be a U.S. citizen to receive a State Department security clearance, subject to extremely rare limited-access circumstances. But not every government or defense-related position requires a clearance; the requirement depends on the duties. The State Department distinguishes clearance positions from public-trust and nonsensitive positions.

ITAR or EAR alone is not a U.S.-citizens-only hiring rule. The Justice Department says these export-control regimes regulate access to controlled items but do not require employers to hire only citizens. An employer may need government authorization before giving some workers access, yet it should assess that requirement for the relevant position rather than turning “U.S. person” into “U.S. citizen.” DOJ’s export-control hiring guidance also advises employers to keep the export-compliance assessment separate from Form I-9 verification.

Automation does not make the exclusion neutral

A citizenship restriction can appear in the public ad, a recruiter’s instructions, a staffing-agency search or an application knockout question. If an applicant tracking system automatically rejects everyone who selects “U.S. citizen” while advancing temporary-visa candidates, automation is only the mechanism; the selection rule remains citizenship-based.

HR teams should inspect both the displayed wording and the configured logic:

1. Identify every citizenship, immigration-status and sponsorship question.
2. Record the legitimate purpose of each question.
3. Test every answer path, including “U.S. citizen” combined with “does not need sponsorship.”
4. Require written legal support for any status-specific restriction.
5. Check staffing vendors and job-board copies for unauthorized wording or rule changes.

The enforcement risk is not theoretical. In 2026, the DOJ announced a $3.2 million settlement with OpenAI and its subsidiary Statsig addressing allegations that their PERM recruitment favored temporary-visa holders and discouraged U.S. workers. DOJ said fewer than 10 positions were involved, but its investigation found that the companies omitted those jobs from the usual external careers site, required mailed paper applications and used late-night radio advertising. The settlement provided for a $1.2 million civil penalty, a $2 million back-pay fund and changes to recruitment practices. A settlement resolves allegations; it is not the same as a court judgment after trial.

What a candidate can do

If a posting appears to exclude U.S. citizens:

• Save the complete ad, URL, date, employer name and requisition number.
• Capture the application questions and any automatic rejection message.
• Keep recruiter emails or messages stating a visa preference.
• Ask a neutral written question: “Is this role restricted by a specific law or government contract, or is the requirement about work authorization or sponsorship?”
• Contact the DOJ’s IER worker hotline at 1-800-255-7688. Its FAQ says an INA charge must generally be filed within 180 days of the alleged discrimination.
• Consider contacting the EEOC or the relevant state or local civil-rights agency if the facts also suggest national-origin discrimination.

Unusual wording does not, by itself, prove a violation. The employer may have a documented exception, and the applicable law depends on the employer, position and facts. But “visa holders only” is not an ordinary sponsorship statement. It warrants preserving the evidence and seeking prompt, qualified review.
