My mother in the Philippines is daignosed with stage 4 Bladder cancer and was told by her oncologist that she has only 9 to 12 months to live. I want to bring her here to United States for a more aggressive cancer treatment. How and where can I get a visa for her.

You can get B2 (medical visa) visa from the U.S. Embassy in your country. There are some requirements like letters from your local hospital and from the doctor in the U.S. You should visit the embassy or go to their web site to find out the requirements.
