Sample Letter for B2 Visa Extension: Request Due to Medical Condition

Dear U.S. Citizenship and Immigration Services,

My name is Maria Gonzalez, holder of a B2 tourist visa (No. 12345678), issued on March 12, 2024, with an expiration date of September 12, 2024. I entered the United States on March 15, 2024, to visit family. During my stay, I was diagnosed with stage‑II lung cancer on April 20, 2024, at the University Hospital in Los Angeles. The doctors have recommended a rigorous chemotherapy regimen that will continue through July 2024, followed by radiation therapy and recovery time.

Because the treatment schedule is fixed and requires my continuous presence in the U.S., I respectfully request an extension of my B2 visa until September 30, 2024. This additional period will allow me to complete my medical care, attend necessary follow‑up appointments, and begin my gradual return to work. I have included the following supporting documents: a doctor’s treatment plan, hospital admission receipt, and a letter of approval from my doctor to stay in the U.S. for the duration of my treatment.

Rest assured, I will adhere to all U.S. immigration regulations and I wish to return to my home country once my treatment concludes. I appreciate your consideration of my request and will be available for any further information you may need.

Sincerely,
Maria Gonzalez

Sample Letter for B2 Visa Extension: Family Emergency – Deceased Relative

Dear USCIS Officer,

I am John Smith, a holder of a B2 tourist visa (Visa No. 87654321) that expired on December 31, 2024. I entered the United States on November 5, 2024, to spend time with my sister. Unfortunately, my father suffered a sudden heart attack and passed away on November 20, 2024, in New York. The funeral is scheduled for December 4, 2024, and I wish to remain until the burial ceremonies conclude to support my grieving family.

To substantiate my request, I am enclosing a copy of the death certificate, funeral program, and my travel itinerary showing planned return by December 15, 2024. I respectfully ask for a visa extension until December 20, 2024. I will make every effort to return home promptly, and I am committed to complying with U.S. immigration law.

Thank you for your understanding and assistance during this difficult time. I am ready to provide any additional documentation you may require.

Sample Letter for B2 Visa Extension: Travel Restrictions / International Flight Issues

Dear U.S. Citizenship and Immigration Services,

I am Samantha Lee, traveler under a B2 visa (Visa No. 11223344). I entered the U.S. on June 1, 2024, for a medical conference. Upon arrival, my return flight to Singapore was abruptly canceled due to ongoing international travel restrictions stemming from the recent outbreak. Airline X issued a refund that will only be credited after a 60‑day waiting period, preventing my timely exit.

Given these unforeseen circumstances, I request an extension until July 15, 2024, to secure and complete my travel arrangements. A copy of the airline’s cancellation notice, a proof of refund issuance, and a revised flight itinerary (once booked) are attached for your reference. I remain committed to leaving the U.S. as soon as my flight is confirmed.

I appreciate your consideration and assure you that I will not overstay my authorized period. Thank you for your assistance.

Sincerely,
Samantha Lee
