Treating U.S. Patients via Telehealth as a Foreign-Licensed Physician: What to Know

Cross-border telehealth comes with more rules than many clinicians expect. We break down key restrictions for foreign-licensed physicians treating U.S. patients.

Treating U.S. patients from abroad might seem like a modern solution to global demand for care, but the legal requirements are complex and vary widely by state. If you’re licensed abroad and considering a telehealth practice focused on U.S. patients, here’s what to understand about state and federal law.

The Core Rule: You Must Be Licensed Where the Patient Is

If your patient is physically located in a U.S. state, even temporarily, you generally must be licensed, or hold a permit or registration, in that state. That’s true even if you’re practicing from another country.

Medical practice is regulated at the state level, and most states apply their existing rules to telehealth just as they would for in-person care. Some states offer limited exceptions or telehealth-only registrations, but those allowances are narrow and not widely available. 

Thus, if a New York–based patient takes a vacation to Illinois and connects with you virtually while in Chicago, Illinois law applies. Unless you’re licensed or registered in Illinois, or Illinois provides a specific exception, you likely cannot legally provide care during that encounter.

Practicing From Abroad Comes With Extra Hurdles

While being physically located outside the U.S. doesn’t disqualify you from treating U.S. patients, it does introduce legal and practical limitations even if you obtain the required state license(s). For example, prescribing controlled substances generally requires both state licensure and Drug Enforcement Administration (DEA) registration, as well as compliance with evolving federal telemedicine regulations. 

DEA registration requires a U.S. practice address, making it difficult to maintain if you reside abroad.  And while the DEA has temporarily extended certain telemedicine prescribing flexibilities through December 31, 2025, these flexibilities don’t eliminate the underlying licensure and registration requirements, and it remains uncertain what rules will apply after that date.

You may also face limitations from your malpractice insurer. Many policies exclude coverage for care delivered while the physician resides abroad. If you’re physically outside the U.S. during the visit, traditional Medicare will not pay for the service (with very narrow statutory exceptions). You’ll also need to comply with both HIPAA and any cross-border data privacy laws in your country of residence. These additional requirements can complicate your regulatory obligations and increase risk.

Working With U.S.-Licensed Physicians Isn’t Always a Workaround

Partnering with a U.S.-based physician does not eliminate your obligation to be licensed in the patient’s state if you’re performing any clinical activities. Diagnosing, treating, prescribing, or even conducting chart reviews with patient interaction are typically classified as practicing medicine. In most states, those tasks are limited to individuals licensed within that jurisdiction.

Some states permit limited “consultation-only” roles for out-of-state or foreign-licensed physicians; however, these exceptions are narrow and typically confined to non-patient-facing input at the request of a U.S.-licensed provider. Even offering a second opinion can qualify as practicing medicine if it involves direct patient interaction, especially if you provide a diagnosis or treatment recommendation. The safer approach is to offer recommendations behind the scenes, while the in-state provider remains fully responsible for patient interaction and treatment decisions.

If you’re contributing only administrative or business services, a management services organization (MSO) structure may help. However, MSOs must be carefully drafted to avoid violating fee-splitting or corporate practice of medicine laws. Franchise models or telehealth startups often fail to clearly outline this, so a thorough legal review is essential. 

What Happens If You Ignore the Rules?

Even if you’re located outside the U.S., state medical boards can still take action if you provide unauthorized care to patients in their state. Practicing without a license may result in cease-and-desist orders, fines, or public disciplinary actions. If you ever apply for U.S. licensure or work with a U.S.-based telehealth company, those enforcement actions could resurface and limit your options. Some states also investigate the U.S.-based partners of unlicensed clinicians, which can put your collaborators at risk as well.

Practical Next Steps

If you’re serious about treating U.S. patients, these practical steps can help you minimize risk and build a compliant practice:

• Pursue U.S. licensure, typically via the USMLE and state credentialing processes
• Use the Interstate Medical Licensure Compact (IMLC) to obtain multistate licenses if you qualify
• Review each target state’s licensing rules, including whether exceptions or telehealth registrations are available
• Confirm your malpractice insurance covers telehealth, out-of-state, or international care
• Comply with prescribing laws, particularly around controlled substances
• Make sure your telehealth services meet HIPAA and any cross-border data privacy obligations
• Avoid advertising that you serve “all U.S. states” unless you’re licensed in each one
• Use robust documentation, informed consent, and role disclaimers to clarify your scope of services.
