Trabalho não autorizado nos EUA: como o USCIS detecta e penaliza

Working in the United States without proper authorization is one of the most consequential violations an immigrant can commit. For those in temporary status, waiting in the green card queue, or already processing an adjustment of status, a single episode of unauthorized employment can block the entire immigration trajectory – sometimes permanently. The rule seems simple on paper, but the definition of what counts as illegal work is broader than most foreign nationals imagine, and USCIS today has multiple channels to identify these violations.

USCIS defines unauthorized employment as any work or service provided to an employer within the United States by a foreign national who does not have authorization to accept employment, or who is working beyond the period or scope of the authorization they hold. The definition covers everything from a single day’s work to the active operation of one’s own business, and applies both to those who never sought authorization and to those who exceeded the permission they received.

What Counts as Unauthorized Work

The first trap lies in understanding what is considered employment under U.S. immigration law. It goes far beyond signing a contract with a registered company.

Working Without an EAD or Employment-Based Status

Accepting employment from a U.S. employer without valid authorization – whether through a status such as H-1B, L-1, O-1, or J-1 with specific permission, or through the Employment Authorization Document via Form I-765 – is the classic and most common form of violation. This applies even if the salary is informal, paid in cash or under the table, and even if the hiring company is unaware of the worker’s status. Civil and administrative liability falls on both sides, but the immigration burden falls entirely on the foreign national.

Self-Employment, Freelancing, and Startups

Establishing or running a business in the United States without work authorization is considered unauthorized employment, even if the operation is part-time. This includes remote freelancing from U.S. soil, even when the client is abroad and payment goes into a foreign account. The service is being performed on U.S. territory, and that is the geographical reference USCIS applies.

The same reasoning extends to actively creating companies: registering an LLC, hiring employees, signing commercial contracts, or appearing publicly as an operational founder can constitute unauthorized work. The act of incorporating a company, in isolation, is not problematic; what matters is active participation in daily decisions and revenue generation.

Volunteer Work

True volunteering does not require authorization. The concept, however, is narrow: the activity must be traditionally voluntary, with no expectation of present or future compensation, and performed for an organization whose mission is humanitarian, religious, or charitable. Occupying a role that would normally be paid – even for free, even just to gain experience – is considered unauthorized work, because it displaces wages that would belong to a legally eligible worker.

Passive Investment

Foreign nationals may maintain financial investments in the U.S. without work authorization. Buying stocks, holding ETFs, owning Treasury bonds, investing in real estate funds, and even participating in a private company as a passive investor are all permitted activities. The red line is active participation: recurring day trading, direct portfolio management for third parties, and operational involvement in an invested company cross that line and may be characterized as unauthorized work.

The Wettasinghe Case

In Wettasinghe v. INS, a student violated his status by acquiring a fleet of six ice cream trucks and leasing them to street vendors. The court found that his active participation – buying ice cream, supplying the vehicles, occasionally driving one – constituted unauthorized self-employment, and the deportation was upheld. The case is still cited today as a reference for what distinguishes passive investment from active operation, and serves as a warning to any foreign national considering entrepreneurship while awaiting authorization.

How USCIS Finds Out

The notion that informal work is invisible to the U.S. government does not reflect the operational reality of the system. There are multiple active detection channels, and the cross-referencing between them has grown more sophisticated every year.

Tax Records

Data cross-referencing between the IRS and USCIS is the most common source. Anyone who receives a Form 1099 or W-2 leaves an automatic tax trail. USCIS may, in the course of an adjustment of status petition or visa renewal, request IRS transcripts or ask the applicant directly for their tax history from recent years. When there is a discrepancy between the maintained status and declared income, the officer may issue a detailed RFE or deny the petition.

E-Verify and the Social Security Administration

The E-Verify system, used by employers in several states on a mandatory basis, cross-references Form I-9 data with the Department of Homeland Security and Social Security Administration databases. Attempts to use an invalid, expired, or third-party SSN generate alerts that escalate through interagency channels. Even employers who do not participate in E-Verify remain required to maintain Forms I-9 and can be audited by Immigration and Customs Enforcement (ICE) for evidence regarding each employee.

Social Media and Public Exposure

Posts on Instagram, Facebook, LinkedIn, TikTok, and Twitter are among the most commonly used sources in consular interviews and petition reviews. Photos in work environments, testimonials in institutional videos, product announcements, and even mentions in colleagues’ profiles can be referenced in RFEs or used in adjustment of status interviews. The combination of OSINT (open-source intelligence) and internal data cross-referencing is now routine in sensitive petitions.

Tips and Reports

Coworkers, former employers, neighbors, ex-spouses, and even strangers can file reports through official channels. USCIS and ICE receive anonymous tips, and opened investigations may include additional inquiries and cooperation with state labor enforcement agencies.

Consequences for Immigration Status and the Green Card

The consequences of unauthorized work extend across every stage of the foreign national’s immigration journey.

Bar to Adjustment of Status

INA 245(c)(2) and (c)(8) establish that foreign nationals who have accepted unauthorized employment are barred from adjusting status in the U.S., with specific exceptions under INA 245(k) – applicable mainly to employment-based categories EB-1, EB-2, EB-3, and EB-4 under restricted conditions, and to immediate relatives of U.S. citizens under the INA 245(c)(2) rule. For most family-based petitioners in preference categories (F-1 through F-4) and many employment-based petitioners outside these exceptions, the violation immediately closes the door to adjustment and pushes the applicant toward consular processing – with possible imposition of three- to ten-year bars for accumulated unlawful presence.

Ineligibility for Extension or Change of Status

Foreign nationals seeking to extend H-1B, change to another nonimmigrant category, or transition between statuses must demonstrate full maintenance of prior status. Unauthorized work breaks that chain, and USCIS may deny the extension or change based on the prior violation, even when the petition itself would otherwise be approved on its merits.

Future Inadmissibility

The violation history is recorded and may surface in future consular visa applications, ESTA renewals, naturalization interviews, and green card reviews. The bar may be absolute in cases involving associated document fraud (INA 212(a)(6)(C)), with very limited waiver possibilities.

Deportation

Removal proceedings may be initiated when the violation is detected, especially when there are additional elements such as identity theft, tax fraud, or failure to comply with a notice to appear. ICE prioritizes cases with aggravating factors, but unauthorized work alone can also lead to removal proceedings in more active jurisdictions.

F-1 Students and Dependents

The F-1 employment framework is particularly restrictive. On-campus work is permitted for up to 20 hours per week during the academic term and full-time during breaks, always within SEVIS rules. Off-campus work requires specific authorization via CPT, OPT, or STEM OPT extension, all with formal requirements and fixed deadlines. Self-employment under F-1 without approved OPT is one of the most frequently detected violations by USCIS in subsequent adjustment petitions.

Dependents follow specific rules:

  • F-2: F-1 spouses and children may not work under any circumstances.
  • J-2: J-1 dependents may apply for work authorization via Form I-765, provided the income earned is not necessary to support the J-1 principal.
  • H-4: H-1B spouses may work when the principal holds an approved I-140 or is in an H-1B extension beyond six years under AC21.
  • O-3: O-1 dependents have no work authorization.
  • L-2: L-1 spouses have automatic work authorization tied to the I-94 since 2022, with no need for a separate EAD.

What to Do If Form I-485 Was Denied Due to Unauthorized Work

When adjustment of status is denied based on unauthorized employment, there are limited avenues for defense. Form I-290B, Notice of Appeal or Motion, allows requesting reconsideration or reopening, but the window is short – typically 30 days from the date of notification – and the burden of proof is high. The defense is typically built around three axes: contesting the characterization of the work as unauthorized, demonstrating eligibility for one of the exceptions under INA 245(k), or proving eligibility as an immediate relative of a U.S. citizen with the protection of INA 245(c)(2).

In cases with strong elements, it is possible to file a new petition after resolving the underlying issue, especially if the applicant can demonstrate good faith and the absence of fraudulent elements. The choice between appealing the decision and refiling based on new facts depends on available time, immigration history, and the availability of evidence.

How to Obtain Legitimate Authorization

The Employment Authorization Document (EAD) is the general work permit in the U.S. and is requested via Form I-765. It may be granted to holders of a pending I-485, asylum and refugee beneficiaries, dependents in specific categories (J-2, H-4 with conditions, K-3, K-4), and students on OPT or special CPT. Processing times vary by category and responsible service center.

For those in visitor status (B-1/B-2) who wish to work, the correct path is to request a change of status to an appropriate employment category – H-1B, L-1, O-1, E-2, or another – before beginning any compensated activity. Working under B-1/B-2 is one of the most heavily penalized violations, frequently resulting in visa cancellation and a bar on readmission.

The Principle That Protects Your Future

The practical rule is simple: no verbal authorization, no employer promise, and no financial need justifies working without documentation. The cost of informal income for a few months may be the permanent loss of a green card that took years to build. When there is doubt about whether a given activity counts as work – investment, volunteering, freelancing, business partnership – the conservative reading of the USCIS Policy Manual and consultation with a licensed professional are the least expensive path in the long run.
