Hiring decisions in the United States are governed by a combination of federal and state employment laws designed to prevent unlawful discrimination while ensuring employers comply with immigration requirements. Yes, in some situations. It can be illegal to deny someone a job based solely on citizenship status in Pennsylvania if federal law prohibits that type of discrimination. However, there are important exceptions. Certain jobs are legally restricted to U.S. citizens, and employers may also require applicants to have valid authorization to work in the United States. Because employment discrimination and immigration compliance are largely governed by federal law, the same general rules apply in Pennsylvania as they do across the country.

Understanding Citizenship Status Discrimination
Citizenship status discrimination occurs when an employer treats an applicant or employee differently because they are or are not a U.S. citizen.
Federal law protects certain categories of work-authorized individuals from unlawful citizenship status discrimination during hiring, firing, recruitment, or referral for employment.
However, these protections do not apply in every circumstance, and employers may still verify that applicants are legally authorized to work in the United States.
Work Authorization vs. Citizenship
Citizenship and work authorization are separate legal concepts.
Examples of individuals who may legally work in the United States include:
- U.S. citizens.
- Lawful permanent residents (green card holders).
- Refugees.
- Asylees.
- Certain nonimmigrant visa holders with employment authorization.
- Other individuals authorized to work under federal immigration law.
An employer generally has the right—and often the legal obligation—to confirm that every employee is authorized to work, regardless of citizenship.
When Can an Employer Require U.S. Citizenship?
In some situations, yes.
Certain federal laws, government contracts, national security requirements, or other legal provisions may require that specific positions be filled only by U.S. citizens.
Examples may include:
- Certain federal government positions.
- Jobs requiring specific security clearances.
- Positions where federal law expressly limits employment to U.S. citizens.
When a legal requirement exists, an employer may lawfully restrict hiring to U.S. citizens.
When Citizenship-Based Hiring Decisions May Be Illegal
An employer may violate federal employment laws if they refuse to hire a qualified, work-authorized applicant solely because the applicant is not a U.S. citizen when no legal citizenship requirement applies.
Examples of potentially unlawful conduct include:
- Rejecting an authorized worker solely because they hold permanent resident status.
- Preferring U.S. citizens without a lawful justification.
- Applying different hiring standards based on citizenship status.
- Refusing to consider eligible applicants because they are refugees or asylees.
Whether discrimination occurred depends on the facts, the employer’s reason for the decision, and the applicable federal law.
Pennsylvania’s Role
Pennsylvania follows federal employment discrimination and immigration laws regarding citizenship status in most employment situations.
Employers operating in Pennsylvania must comply with:
- Federal immigration verification requirements.
- Federal anti-discrimination laws.
- Applicable Pennsylvania employment laws.
- Other relevant workplace regulations.
Pennsylvania does not create separate immigration work authorization rules that replace federal law.
Employer Responsibilities
Employers should adopt hiring practices that are both lawful and consistent.
Good practices include:
- Verifying work authorization for all new hires.
- Applying hiring standards equally to all applicants.
- Avoiding unnecessary citizenship requirements.
Consistent hiring procedures help reduce the risk of discrimination claims while ensuring compliance with immigration laws.
Employee Rights
Applicants and employees who are legally authorized to work may have protections against unlawful discrimination based on citizenship status.
If an individual believes they were denied employment because of unlawful citizenship status discrimination, they may have the right to seek assistance through the appropriate federal agency or pursue other legal remedies where permitted by law.
The available remedies depend on the facts of the case and the applicable statutes.
Why Legal Advice Is Important
Employment discrimination and immigration compliance involve complex legal rules that vary depending on the employer, the position, and the applicant’s immigration status.
Employers should seek legal guidance when developing hiring policies, particularly if a position may require U.S. citizenship under federal law. Likewise, applicants who believe they experienced unlawful discrimination should consider consulting an employment attorney to understand their legal rights and available options.
Conclusion
Denying a job based solely on citizenship status in Pennsylvania can be illegal if federal law protects the applicant from citizenship status discrimination and no lawful citizenship requirement applies. At the same time, employers are generally permitted—and often required—to verify work authorization and may lawfully limit certain positions to U.S. citizens when federal law specifically requires it.
