My daughter, 11 years old, needs cancer treatment in Boston, MA where she have already been accepted by the Boston Children Hospital and the Dana Farber Cancer Institute. We plan to temporarily relocate to Boston for aprox. 3-6 months to complete treatment. My daughter, my wife and I are Swiss citizens. With us in Switzerland lives my mother-in-law, 64 years of age and economically dependant from me. She is a Colombian citizen and has a Swiss residency permit. What approach do you recommend in order to get a tourist visa for her asap as we need to initiate treatment in Boston asap?
Thanks a lot for your assistance. Best regards, Tom
