Work Permit in US Law: The Legal Framework for Legal Employment in the USA

What is a work permit under US law? This guide explains US work visas, EAD (Emergency Admission Fee), Green Cards, student work, H-4 (spouse's right to work) regulations, the EAD process for those awaiting asylum applications, and employer's I-9 obligations.

In US law, a work permit is not limited to a single card or application type. The most common confusion in practice is believing that "work visa," "work permit," "Employment Authorization Document (EAD)," and "Green Card" are all the same thing. However, in US law, a foreigner's right to work sometimes stems directly from their immigration status, sometimes requires a separate EAD , and sometimes is only possible for a specific employer and under a specific category. According to the US Department of State, foreigners wishing to work temporarily in the US must first meet the appropriate visa category for the planned job; USCIS explicitly states that the EAD is one of the documents that authorizes a person to work in the US for a specific period. (Travel)

Therefore, there is no single answer to the question, "How do I get a work permit in America?" A person can work under a temporary employment status dependent on an employer, such as H-1B; a student can only work under specific education-related conditions; an asylum seeker can request an EAD after the waiting period; and a Green Card holder can, as a rule, work indefinitely without applying for a separate work permit. Similarly, while the right to work is directly derived from the spouse's status in some cases, some spouses also a Form I-765 application. Therefore, at the intersection of US labor law and immigration law, the first what status the individual holds . (uscis.gov)

A work visa and a work permit are not the same thing

In U.S. law, a work visa often nonimmigrant visa category that allows entry into the country for a specific job purpose. According to the Department of State's temporary worker visas page, a foreign national wishing to come to the U.S. for a fixed-term job must first qualify for the correct visa category; most temporary worker categories also require a U.S. employer to submit a petition to USCIS and obtain approval. According to the same official source, there are currently 11 temporary worker visa categories, and in many applications, the process begins with the employer Form I-129 . (Travel)

In contrast, "work authorization" is a broader concept. According to USCIS, some foreigners obtain authorization to work directly from their status; others must also Form I-765 . The USCIS EAD page clearly states that EAD is one way to prove authorization to work in the U.S. for a specific period, but not every foreigner who can work is required to obtain an EAD. In particular, for nonimmigrant statuses tied to specific employers, the right to work may arise from the status itself, not from a separate EAD application. (uscis.gov)

Therefore, equating a work visa with a work permit is legally incorrect. For example, a person with H-1B status can work for a specific employer due to their status; whereas a person awaiting asylum can only work after the necessary periods have passed and they have received an EAD (Emergency Assistance Decision). Similarly, a Green Card holder already has the right to permanent work; however, an F-1 student cannot freely work in any job and under any circumstances. This is precisely the logic of the US system: the right to work is not a uniform permit, but an authorization that varies according to immigration status. (Travel)

How does the right to work in the US arise?

In U.S. law, the right to work essentially arises in one of three main ways. The first is when work is status-dependent and directly authorized . The second is when a person must also obtain an EAD ( Emergency Authorization for Work) to have the right to work . The third is when a person already has permanent work authorization as a lawful permanent resident , i.e., a Green Card holder. Various sources from USCIS clearly illustrate this three-way distinction. ( uscis.gov )

In status-based work authorization, an individual can work thanks to a specific immigration category. According to the Department of State's explanation of temporary worker visas, categories such as H-1B, H-2A, H-2B, H-3, L, O, P, and Q are used for specific types of work. The common feature of these categories is that the individual has the right to work based on category and often employer, rather than a "general" freedom to work in the U.S. For example, H-1B is for specialized occupations, H-2A for temporary agricultural work, and L for intra-company transfers (travel)

The situation is different for work authorizations requiring an EAD (Employment Authorization Form). According to USCIS's explanations of I-765 and EAD, certain foreigners Form I-765, Application for Employment Authorization, , and if approved, they are sent a work permit. This category can include many groups such as those awaiting asylum applications, those with pending adjustment of status applications, some spouses, and certain students. Therefore, the right to work doesn't always stem from the classification written on the visa sticker; sometimes it needs to be requested separately within the US. (uscis.gov)

Permanent employment authorization is seen in the Green Card regime. USCIS explicitly states that a Green Card grants an individual the right to live and work permanently in the United States. Furthermore, according to USCIS I-9 sources, a lawful permanent resident can prove both their identity and employment authorization with appropriate documentation, such as a Green Card; the employer is generally not required to re-verify this person's employment authorization at regular intervals. This demonstrates that the Green Card is one of the strongest employment statuses under labor law. (uscis.gov)

Temporary work visas: The baseline for entering the U.S. for work

Temporary work visas are the most classic way to enter the United States from abroad for work purposes. According to the Department of State, temporary worker visas include categories H-1B, H-1B1, H-2A, H-2B, H-3, L, O, P-1, P-2, P-3, and Q-1. The same source states that most applications require employer sponsorship and USCIS petition approval; some categories also require labor certification from the Department of Labor. (Travel)

The legal rationale behind these categories is not the “general free movement” of foreign labor, but rather their limited acceptance for specific economic or professional needs. For example, H-1B requires at least a bachelor's degree or equivalent, while H-2A and H-2B categories are geared towards temporary or seasonal work needs. Category L requires the applicant to have worked abroad for at least one year within the same group of companies in the last three years. Categories O and P address more specific areas such as exceptional talent, sports, or leisure activities (e.g.,travel)

The key takeaway here is that a temporary work visa does not authorize its holder to “work any job they want in the U.S.” In most cases, the right to work is limited to a specific position, a specific employer, and a specific category. Therefore, a violation of status can occur not only by exceeding the visa duration but also by working outside the permitted scope of employment. Decisions such as changing jobs, taking on additional work, or diversifying positions in the U.S. can jeopardize the right to work if they are not compatible with immigration status. This conclusion stems from the Department of State’s category-based system and USCIS’s specific employer-dependent work logic. (Travel)

People who are able to work due to their status

Under U.S. law, some foreigners can work without also applying for an EAD (Employment Admissions Law). The USCIS EAD page explicitly states this: if a person has nonimmigrant status that allows them to work for a specific employer, they may not need to apply for an EAD. The same approach is found in the USCIS unauthorized employment policy section, which states that some nonimmigrant categories can work “incidentally to status,” but this is subject to regulatory limitations. (uscis.gov)

Typical examples of this group are petition-based temporary employment classes such as H, L, O, P, and similar. If a person is accepted under these statuses, their employment stems from that status. Furthermore, the USCIS policy manual certain E and L dependent spouses . This means that some E and L spouses are considered authorized to work even without obtaining an EAD card. The USCIS temporary nonimmigrant workers page also explicitly states that certain E and L dependent spouses are considered "employment authorized incident to status" (uscis.gov)

However, not all spouse statuses are the same. According to USCIS's explanation of H-4 dependent spouses, spouses with H-4 status cannot automatically work; they can only Form I-765 . In other words, while spouses with E and L status have a broader "right to work by status," the system is narrower for H-4 spouses, and in most cases, a separate application is required. This distinction is very important in practice because the assumption that "spouse has status, therefore I can work" is not true for every category. (uscis.gov)

What is EAD and how does Form I-765 work?

In the United States, the most well-known document regarding work permits the Employment Authorization Document (EAD). According to the official definition of USCIS, an EAD is a card, usually Form I-766 , that proves the holder is authorized to work in the United States. While not the sole source of work authorization, the EAD is the most visible and practical proof for many categories. USCIS also emphasizes that the EAD proves authorization to work for a specific period. (uscis.gov)

The primary application form used to request this card Form I-765. The USCIS I-765 page states that the application can also be submitted online through an account and that the work card will be sent to the address specified in the application. The form itself also asks the applicant to select an eligibility category; this indicates that I-765 is not a "general work permit application" but a request based on specific legal grounds. Therefore, completing I-765 alone does not create the right to work; the applicant must first fall into a category recognized by law. (uscis.gov)

USCIS also implements an automatic extension system for some EAD renewals . According to a 2025 USCIS announcement, individuals who apply for a timely renewal of an EAD that has expired under appropriate conditions may have their authorization to work temporarily extended beyond the card's expiry date in certain categories; USCIS has stated that this extension can go up to 540 days in some cases . This is very important in practice because the physical expiry date of the EAD card and the legally extended authorization to work may not be the same thing. ( uscis.gov )

Work permits for those awaiting Green Card applications

A significant number of individuals who have applied for permanent residency in the United States face the issue of the right to work while their application is pending. According to USCIS's "While Your Green Card Application Is Pending" and employment-based Green Card resources, a pending Form I-485 can generally apply for work permits and other benefits such as advance parole. In other words, having applied for a Green Card can open the door to work permits even before the card is issued. (uscis.gov)

In this case, the tool is most often Form I-765 . USCIS states that those with pending I-485 forms can generally apply for an Adjustment of Status (EAD). Therefore, for those awaiting an Adjustment of Status application, the key to working in the US is to request a work permit consistent with their current application. However, the important point is this: being awaiting a Green Card application does not always automatically mean freedom to work without documentation; the EAD process remains important in most cases for initiating and proving the right to work. (uscis.gov)

Work permits for students: Limits of the F-1 regime

Work permits for international students studying in the United States are one of the most misunderstood aspects. According to USCIS's "Students and Employment" and policy manual resources, F-1 students can work on-campus or off-campus under certain conditions; there are also practical training . The USCIS policy manual states that F-1 students can work under three types of practical training: Curricular Practical Training (CPT), pre-completion OPT , and post-completion OPT. M-1 students, however, can work more narrowly, solely for practical training purposes. (uscis.gov)

OPT is the most well-known form of student work. According to USCIS's explanation of OPT, eligible F-1 students for up to 12 months ; this can encompass both pre- and post-graduation periods. For certain students earning degrees in STEM fields, USCIS a 24-month STEM OPT extension . This can significantly extend the total practical training time; however, it is only possible if the appropriate STEM degrees and other requirements are met. (uscis.gov)

The key point for students is that not all work is automatically permitted. USCIS archives and I-9 resources emphasize that F-1 students need to obtain an EAD from USCIS in most cases to be able to work under the OPT program. In other words, student status does not grant unlimited freedom to work; work is only possible through regulated education-related channels and with an EAD when necessary. Therefore, the idea of ​​"working any job, even part-time," can be risky in terms of immigration status for F-1 holders. (uscis.gov)

Work permits for asylum seekers and refugees

Another important group seeking work permits in the U.S. are those within the asylum regime. Here, two distinct statuses must be carefully distinguished: an asylum applicant and an asylee are not the same. According to the USCIS asylum page, an asylum applicant processes their application under either an affirmative or defensive asylum application; to work, they must file an I-765 at the appropriate time. In contrast, according to the USCIS I-9 and asylee sources, an asylum seeker, or asylee, possesses the right to work by virtue of their status. (uscis.gov)

The timeframe is crucial in pending asylum applications. According to official USCIS statements, a general 150 days is required for an EAD (Emergency Work Permit) request based on a pending asylum application; the total time for the EAD to be granted 180-day rule. USCIS also notes that applicant-caused delays can affect this timeframe. Therefore, the idea that a work permit can be obtained immediately after an asylum application is incorrect; the asylum EAD process is subject to its own specific timeline. (uscis.gov)

In contrast, the situation is more favorable for asylee and refugee groups. USCIS's I-9 guidance states that refugees and asylum seekers considered eligible for employment due to their status , and therefore their right to work stems from their status. In other words, if a person is no longer an "asylum applicant" but an "asylee," the legal basis for their right to work becomes much stronger. This distinction is a fundamental legal difference between asylum seekers in the application phase and those who have received protection orders. (uscis.gov)

H-4 Right to work of spouses and dependent spouses

In U.S. immigration law, the right to work for dependent spouses is not the same for all categories. According to the USCIS H-4 dependent spouse page, only certain H-4 spouses can obtain EAD by filing I-765; this requires the H-1B spouse to have reached certain stages. Therefore, H-4 status alone does not automatically create the right to work. This point is very important in practice because many families assume that the right to work will automatically arise after arriving in the U.S. with dependent spouse status. (uscis.gov)

In contrast, the USCIS policy manual states that work authorization for certain E-1, E-2, E-3, and L-2 dependent spouses is recognized based on their status. USCIS also explains that, as of 2022, I-94 coding for E and L spouses plays a role in demonstrating this work authorization. Therefore, the most critical question regarding dependent spouses is not "does the spouse have status?" but "what kind of spouse status does the spouse have?". Despite the same "dependent spouse" appearance, there are significant differences in work authorization among H-4, E, and L spouses. (uscis.gov)

Employer's responsibility: Form I-9

In the United States, obtaining a work permit isn't solely a foreign national's issue; employers also have significant verification responsibilities. According to USCIS's Form I-9, Employment Eligibility Verification page, employers must verify both the identity and work eligibility of individuals they hire in the US. USCIS explicitly states on the same page that this form is used for every employee hired in the US. This demonstrates that the work permit discussion is not just an immigration matter, but also a field of employment law and compliance obligations. (uscis.gov)

During the I-9 process, employees submit the appropriate documents accepted by USCIS. According to USCIS's definition of acceptable documents, an employee may submit either a List A document showing both identification and authorization to work, or separate List B and List C documents. Green Cards, EADs (Employer's Rights Advice), and certain combinations of I-94 documents are relevant in this context. USCIS also emphasizes that employers should not request unnecessary documents from lawful permanent residents and should not discriminate against them. (uscis.gov)

The result of this system is that it is not enough for a foreigner to simply say "I have the right to work"; this right must be demonstrated with appropriate documentation within the I-9 system. Similarly, an employer cannot rely solely on the employee's statement. Therefore, a work permit in the US is a legal capacity proven both through individual status and documentation. (uscis.gov)

Consequences of unauthorized work and immigration

In U.S. law, unauthorized employment can affect not only the employer-employee relationship but also immigration status. The USCIS unauthorized employment policy manual clearly states that unauthorized employment can have negative consequences in certain adjustment of status cases. The same source notes that some nonimmigrants can only work to the extent permitted by their status; exceeding this limit can cause problems. Therefore, the "I'll fix it later" mentality poses a serious risk, especially for those planning a Green Card or status change. (uscis.gov)

Unauthorized employment arises particularly when individuals, such as tourists, students, or dependent spouses, who do not have the authority to work, actually begin employment. The issue isn't limited to salaried employment; the nature, continuity, and legal standing of the work can become crucial depending on the specific case. Therefore, before starting work in the US, the real question shouldn't be "I found a job," but rather, "Does my current status truly permit me to do this job?" This is a fundamental but often neglected protection mechanism in immigration law. (uscis.gov)

Permanent employment rights: work-based immigration and Green Card

In the United States, the most secure and long-term employment opportunity is ultimately established through permanent residency . According to the Department of State's immigrant visa statement, the US recognizes employment-based immigrant visas . The same official source states that the second-choice category often requires a job offer and Form I-140 from the employer, although exceptions such as the National Interest Waiver are possible in some cases. The Department of State also emphasizes that the general immigration system is divided into categories such as family, work, adoption, special immigration, and diversity visas. ( Travel )

On its employment-based Green Card page, USCIS states that U.S. immigration law offers individuals various pathways to becoming lawful permanent residents through employment. This means that H-1B or other temporary status may not only be a means of short-term employment for some, but also the beginning of an immigration route that later progresses to categories such as EB-1, EB-2, or EB-3. However, this transition is not automatic; it requires a separate petition, the appropriate category, and in some cases, visa bulletin follow-up. (uscis.gov)

Conclusion

In US law, work authorization is not limited to a single card or visa category. For a proper legal analysis, the following distinction must first be made: Is the individual in a temporary employment status tied to a specific employer, in a category requiring EAD (Emergency Work and Development), have limited work rights as a student, be in the asylum process, or possess permanent work authorization as a Green Card holder? In the US system, the right to work can be a natural consequence of immigration status, or it can be a right that must be claimed separately. (Travel)

Therefore, the biggest mistake regarding "work permits in America" ​​is assuming there's a single, uniform formula for every foreigner. However, someone working under an H-1B, an F-1 student, an H-4 spouse, a pending asylee, a pending I-485 holder, and a Green Card holder are not subject to the same legal regime. A successful immigration and work strategy begins not before the job offer, but the fit between your status and the job . The key to legally working in the US is not just finding a job; it's making that job legally feasible with your current status or through the right application. (Travel)
