Medical treatment alone does not usually qualify someone for permanent immigration. Short-term visitor visas (B-2) can allow entry for treatment if properly documented.

In some cases, a humanitarian parole may be requested for urgent medical care. Supporting evidence like doctor letters, treatment plans, and financial ability to cover care is essential. Approval is discretionary and evaluated case by case.

Family-sponsored petitions typically require closer relationships, so an uncle may not qualify for a green card directly. Combining a visitor visa with proper medical documentation is often the most realistic path. Consulting an immigration attorney can help prepare a strong, lawful application.
