Work authorization is a legal permission granted by the U.S. government that allows individuals to work lawfully in the United States. It applies to U.S. citizens, who are automatically authorized to work, lawful permanent residents, and individuals with temporary permits, such as visa holders or asylum seekers. Employers must verify each employee's work authorization before hiring and maintain records proving compliance with federal immigration laws.
HR departments handle work authorization verification through Form I-9, which requires employees to provide acceptable documents proving their identity and employment eligibility. Common documents include U.S. passports, driver's licenses combined with Social Security cards, or Employment Authorization Documents (EADs) for temporary workers.
It refers to the legal right to work in the U.S. as granted by immigration authorities. All employees in the U.S. need valid work authorization. U.S. citizens have automatic authorization, while non-citizens must obtain specific visas, Employment Authorization Documents, or other permits before they can legally work for U.S. employers.
Work authorization depends on your immigration status. U.S. citizens automatically have the right to work. Non-citizens may obtain work authorization through:
Employment visas (like H-1B, L-1, O-1)
Employment Authorization Documents (EAD) via USCIS
Asylum or refugee status
Other immigration programs that permit work
Examples of work authorization include U.S. citizenship, lawful permanent resident status (green card), H-1B visas for specialty workers, L-1 visas for intracompany transfers, Employment Authorization Documents for asylum seekers, and work permits for students on F-1 visas with Optional Practical Training.
The types of work authorization include:
Permanent Authorization: For U.S. citizens and lawful permanent residents
Temporary Authorization via Employment Visas: H-1B, L-1, O-1 visas
Student Work Permits: F-1 OPT (Optional Practical Training)
Asylum-Based Work Permits: Work while asylum application pending
Refugee Work Authorization: Work legally as a recognized refugee
Family-Based Employment Documents: People applying to become permanent residents (adjustment of status) can work while their application is processed
Employers verify work authorization using Form I-9, which requires employees to present acceptable documents proving identity and employment eligibility. Acceptable documents include U.S. passports, driver's licenses with Social Security cards, or Employment Authorization Documents. Verification must occur within three business days of hire.
Employers must verify every employee's work authorization through Form I-9 completion, examine original documents, and maintain I-9 records for audit purposes. They cannot discriminate based on citizenship status among authorized workers or specify which acceptable documents employees must provide. Employers face penalties for hiring unauthorized workers or improper verification procedures.
Work authorization eligibility depends on immigration status and specific circumstances. U.S. citizens and permanent residents have automatic eligibility, while others must qualify through employment visas, asylum or refugee status, family relationships, or special programs that grant temporary work permissions.
