47.2%. That’s the share of America’s internal medicine workforce born outside the United States. In nephrology, it’s 62%. In geriatrics—the specialty HRSA projects at lowest supply adequacy by 2038—it’s nearly 60%.
Immigration policy has quietly become the most powerful workforce allocation mechanism in American medicine, and almost no one in a position to do anything about it seems to have noticed. Or maybe they noticed and decided it was someone else’s problem.
This week, a JAMA study surfaced the structural dependency hospital administrators have been living with for years: the physicians most likely to staff your geriatrics unit, your dialysis center, your sleep medicine clinic are also the physicians most exposed to visa uncertainty, fee proposals, and executive orders that can change faster than a residency application cycle. When 60% of your nephrology workforce requires immigration status that can shift with a single policy memo, workforce planning becomes immigration planning—whether anyone put that on the org chart or not.
The pipeline is already narrowing. Non-U.S. citizen international medical graduates matched to PGY-1 positions at 56.4% this year—the lowest rate in five years—even as their applicant pool grew. The $100,000 H-1B fee proposal, though judicially blocked, already changed hospital behavior: 64% of affected hospitals reported plans to pause, defer, or limit physician recruitment. The fee never took effect. The hiring decisions did.
Here’s the part that makes the structural vulnerability feel less abstract. Foreign-born physicians disproportionately serve the patients least likely to have options. Their panels tilt toward dual-eligible beneficiaries, minority populations, high-poverty ZIP codes, and federally designated medically underserved areas. Immigration disruptions don’t just leave shifts uncovered—they concentrate access losses on the patients who were already waiting longest.
Meanwhile, the domestic workforce that would need to absorb any immigration-driven supply contraction is not exactly standing by with a retention plan. Only 39% of healthcare organizations have a formal, documented strategy for retaining physicians, and most can’t identify who owns it. You can’t have a strategy if nobody owns it—a sentence that sounds like management consulting until you realize it explains why the same positions keep cycling through your recruiting budget.
The week’s other signals fit the pattern of systems operating on assumptions that no longer hold. Medicare’s proposed fee schedule cuts continue to compress margins for independent practices, accelerating the consolidation that has already reshaped specialty care. AI clinical decision-support tools are being deployed faster than validation can follow, with liability landing on the physicians who use them—not the systems that mandated them. PMHNP demand continues to outpace the broader staffing recovery, driven by telehealth models and scope-of-practice arbitrage that traditional physician roles can’t easily replicate.
None of this is happening in isolation. The healthcare system has been running on immigration-sensitive pipelines for decades, treating visa policy as an externality to workforce planning rather than a core input. That worked fine when policy was stable. It works less fine when a single fee change can destabilize subspecialty access in ways that would take a decade of GME expansion to repair.
Compensation strategies, training pipeline expansions, and retention programs cannot independently resolve a supply constraint that operates upstream of all of them. Immigration policy now determines whether physicians enter the U.S. practice pipeline at all—not how they are employed once inside it. And no institutional actor currently owns the integration of immigration strategy with workforce planning at the operational level. Which means no one is responsible for noticing when the math stops working.
The math has stopped working. Somebody’s nephrology chief is going to figure that out on a Tuesday morning when a fellow’s visa doesn’t come through.
P.S. PhysEmp is an AI-powered job board built for physicians and the employers trying to reach them. If you’re a physician exploring what’s actually out there—or a recruiter trying to connect with candidates without shouting into the void—we built the platform to make that process a little more intelligible. Less noise, clearer signals.
