Where a foreign national is undergoing continuing medical treatment in the United States and is unable to depart prior to the expiration of the period of authorized stay, such individual may seek an extension of non-immigrant status by filing the prescribed application with the United States Citizenship and Immigration Services. The request for extension is ordinarily required to be supported by evidence demonstrating that the applicant was lawfully admitted, has maintained valid non-immigrant status, and that the need for continued stay arises from bona fide medical circumstances necessitating ongoing treatment.

In such cases, documentary evidence generally includes a detailed letter from the treating physician or medical institution specifying the nature of the illness or condition, the treatment already administered, the anticipated duration of further treatment, and the reasons why interruption of the treatment or departure from the United States would be medically inadvisable. Copies of medical records, hospital reports, and evidence of appointments and treatment schedules may also be furnished in support of the application.

In addition, the applicant is expected to establish financial capability to bear the expenses associated with medical treatment and living costs during the extended period of stay. Evidence in this regard may include bank statements, proof of income, affidavits of support, sponsorship letters, insurance coverage documents, or any other material demonstrating the availability of sufficient funds without recourse to public assistance.

1) Inquiry concerning U.S. visa requirements for medical treatment: Please provide guidance on the necessary visa classification and the documentation required to verify medical and financial eligibility.

To obtain a U.S. medical visa, you must apply for a B-2 visitor visa via Form DS-160 and attend a consular interview. You must provide a formal letter from a U.S. medical facility outlining the treatment plan, expected duration, and total estimated costs, along with proof from your local doctor that the treatment is necessary and unavailable in your home country. Additionally, you must submit bank statements or financial records proving you can afford all medical and living expenses, while demonstrating “binding ties” (such as employment or property) to prove your intent to return home after treatment. Given the strict documentation requirements, consulting with an immigration attorney is highly recommended to ensure your application is complete.

2) In light of my ongoing medical treatment, I require an extension of my current authorized stay. Please outline the necessary procedures and documentation required to formally extend my non-immigrant status.

To request an extension of stay for medical treatment, you must file Form I-539 with USCIS prior to the expiration of your current I-94 authorization. The application must be supported by a formal statement from your U.S. physician detailing the necessity and expected duration of continued care, as well as evidence of sufficient financial resources to cover all expenses and proof of your intent to return to your home country. Please be advised that those admitted under the Visa Waiver Program (ESTA) are ineligible for extensions; therefore, it is strongly recommended that you consult with a qualified immigration attorney to ensure your filing meets all regulatory requirements.
