When Simple Questions Reveal Complex Problems: The Hidden Risks in Global Mobility

How a straightforward benefits inquiry exposed serious immigration risks—and why expert counsel matters The Deceptively Simple Question The email seemed routine enough: “We have a team member in South Africa who will be pursuing their PhD in the US. They will be working part-time on a few projects while also focusing on their degree. Since this team member will be part-time, we need to determine the appropriate benefits for their situation. Could you please suggest some questions we should be asking?” On the surface, this appears to be a standard HR benefits question. A company wants to do right by an employee pursuing higher education. They’re being thoughtful, asking what benefits make sense for part-time status, seeking guidance on the right questions to ask. But embedded within this innocent inquiry lies a potential immigration violation that could result in visa revocation, deportation, and serious consequences for both the employee and the employer. This is the reality of Global Mobility work: what appears simple rarely is. The Problem Hiding in Plain Sight The client’s question focused entirely on benefits administration. They wanted to know: These are reasonable HR considerations. But they completely missed the fundamental issue: Can this person legally work for the company at all while studying in the United States? The assumption baked into the question, that the employee would simply continue working part-time during their PhD program, ignored the complex web of U.S. immigration law governing international student employment. The client was preparing to design a benefits package for an arrangement that might not be legally permissible. This isn’t a criticism of the client. They did exactly what responsible employers should do: they reached out for guidance when facing an unfamiliar situation. The problem is they didn’t know what they didn’t know. Why This Matters: The Immigration Landmine Here’s the piece everyone missed: could this person even legally work in the U.S. at all? The student in question was planning to pursue a PhD in the United States under an F-1 visa. And that single detail changes everything. F-1 status comes with very specific, and very restrictive, employment rules. Unless a student has explicit authorization, the safe assumption should always be they can’t work for you. During the first academic year, F-1 students are limited to on-campus jobs, up to 20 hours a week when classes are in session. Off-campus work isn’t allowed unless and until they get proper authorization. After that first year, there are only a few narrow paths: Curricular Practical Training (CPT) and Optional Practical Training (OPT). CPT is approved by the university’s international office. It has to be tied directly to the student’s curriculum, think an internship that’s required for a degree or integral to a specific course. OPT, on the other hand, requires both school recommendation and an application to USCIS for an Employment Authorization Document. Neither happens automatically, and both take time. While an F-1 student is physically in the United States, any compensated work, on-site or remote, part-time or full-time, requires that authorization. There’s no gray area just because the work is done over Zoom or for a familiar employer back home. Immigration rules hinge on where the student is, not where the company’s servers or offices are. Working without authorization isn’t a technicality; it’s a status violation. That can lead to the student’s SEVIS record being terminated, loss of F-1 status, and potential visa cancellation. Once that happens, unlawful-presence clocks start ticking, cross the 180-day mark, and you’re looking at multi-year re-entry bars. Employers who knowingly or negligently keep someone on payroll without valid authorization can face civil fines and reputational risk that outlasts the incident. In plain English: one “helpful” decision to let a student keep working remotely could derail a PhD, damage a career, and invite government attention your company doesn’t want. That’s why, in Global Mobility, the right first question isn’t “what benefits apply?” It’s “can we legally pay this person at all?” All because a benefits question seemed straightforward. The Expertise Gap in Global Mobility This scenario illustrates why Global Mobility requires specialized expertise that goes far beyond traditional HR or benefits administration. Traditional HR professionals excel at domestic employment law, benefits design, compensation strategy, and employee relations. They understand ERISA, FMLA, ADA, and the full alphabet soup of U.S. employment regulations. But international student work authorization? That’s not in their wheelhouse, and there’s no reason it should be. Immigration attorneys understand visa categories, work authorization, and compliance requirements. But they may not think holistically about the employment relationship, tax implications, benefits coordination, or business operational needs. Global Mobility specialists sit at the intersection. They recognize when an HR question triggers immigration concerns, when a visa issue creates tax complications, when a relocation plan requires coordination across multiple jurisdictions, and when seemingly simple arrangements hide complex compliance requirements. The value isn’t just knowing the rules, t’s recognizing which rules apply to a given situation. The Diagnostic Process: What Expert Review Reveals When a Global Mobility expert reviews the client’s seemingly simple question, a different set of issues immediately emerges: Immigration Status Analysis Work Authorization Mechanics Structural Considerations Benefits and Tax Complexity Only after addressing these foundational questions does the original benefits inquiry become relevant. And the answer might be: “We need to solve the work authorization problem first, because we may not be able to employ this person at all in the way you’re envisioning.” The Cost of Getting It Wrong The consequences of proceeding without proper guidance extend far beyond the immediate situation. For the Employee: For the Employer: For the Industry: The financial cost of expert consultation, typically a few hundred to a few thousand dollars depending on complexity, pales in comparison to these potential consequences.
