US medical treatment visa (B-2): the documents
Direct answer: The State Department says medical treatment is a permitted purpose on a B-2 visitor visa. At the interview a consular officer may ask for: a diagnosis from a local physician explaining the ailment and why you need treatment in the US; a letter from a US doctor or facility stating they are willing to treat your specific ailment, with the projected length and cost of treatment; and proof that your transportation, medical, and living expenses in the US will be paid.

Medical treatment is a permitted B-2 purpose
The State Department lists medical treatment among the activities permitted on a B-2 visitor visa. So you can apply for a visitor visa to receive treatment, through the same process as any B1/B2: complete the online DS-160, and schedule and attend the interview.
A visa only allows you to travel to a US port of entry and request admission; it does not assess your condition or guarantee issuance or entry — CBP decides admission at the port.

The three kinds of documents the interview may require
The State Department says that if you apply for medical treatment, the consular officer may ask for further documents at the interview, which may include:
- A medical diagnosis from a local physician, explaining the nature of the ailment and why you need treatment in the United States.
- A letter from a physician or medical facility in the United States stating they are willing to treat your specific ailment, and detailing the projected length and cost of treatment (including doctors' fees, hospitalization fees, and all medical-related expenses).
- Proof that your transportation, medical, and living expenses in the US will be paid — such as bank or other statements of income/savings, or certified copies of tax returns (yours or the person or organization paying).

Ability to pay, and ties to your home country
The proof that costs will be paid matters a lot: US medical care is often expensive, and the guidance explicitly asks you to show sufficient funds for treatment and living costs. If another person or organization is paying, provide evidence of their ability to pay.
At the same time, B-2 is still a nonimmigrant visa, so you must meet the general 214(b) requirement to show, through your ties at home (job, family, residence), that you will leave the US after treatment. Medical documents support the purpose and funding; they do not change the principle of qualifying on your ties.

Keep practice in its proper boundary
A mock interview can help you explain your treatment purpose, schedule, and funding clearly; keep the boundary explicit: this is not legal or medical advice, not an embassy service, and cannot assess your condition, decide eligibility, or predict a result. The exact documents are governed by the instructions of the post where you apply and the consular officer's request.

What else do applicants ask?
Which visa do I need to travel to the US for medical treatment?
The State Department lists medical treatment among the activities permitted on a B-2 visitor visa. You apply through the ordinary visitor-visa process: complete and submit the online DS-160, print the confirmation page, and schedule and attend the interview.
What documents should I prepare for a medical-treatment interview?
The State Department says that if you are seeking medical treatment in the United States, the consular officer may ask for: a medical diagnosis from a local physician explaining the nature of the ailment and the reason you need treatment in the United States; a letter from a physician or medical facility in the United States stating they are willing to treat your specific ailment and detailing the projected length and cost of treatment, including doctors' fees, hospitalization fees, and all medical-related expenses; and proof that your transportation, medical, and living expenses in the United States will be paid — bank or other statements of income or savings, or certified copies of income tax returns, either yours or those of the person or organization paying for your treatment.
Can someone else pay for the treatment?
Yes. The State Department says the proof of payment may come from the person or organization paying for your treatment, for example their statements of income or savings or certified copies of their tax returns. Visa applicants must still qualify based on their own ties abroad rather than on assurances from U.S. family and friends.
Can insufficient funds be a reason for refusal?
Yes. The State Department says public charge refusals under INA section 212(a)(4) are less frequent for nonimmigrant visa applications but can occur — and the example it gives is a visa applicant seeking medical treatment in the United States without adequate funds to pay for treatment. To overcome that ineligibility you must demonstrate that you will have sufficient financial support in the United States, and the consular officer reviews the additional evidence you submit.
Treatment may take a while — how long can I stay?
The visa itself does not set your stay. The State Department says that if CBP admits you, the CBP official provides an admission stamp or a paper Form I-94, and you are authorized to stay until the date indicated on it; to request more time, see Extend Your Stay on the USCIS website. Failure to depart on time results in being out of status, automatically voids the visa under INA section 222(g), and may make you ineligible for visas in the future.
What are the official numbers?
Every figure below was read from an official U.S. government page, not from experience or an agency's summary. Fees and rules change — before you actually pay or file, check the primary pages listed under the sources section. One row deliberately carries no number: the State Department has never published a fixed duration for administrative processing.
