Help phu fight against leukemia at the age of 10.

I am an international student. My family has been in the US for a year. My child was recently diagnosed with leukemia and is being treated at the Northwest Children's Hospital in Arkansas. My child's insurance only covers $50,000 and cannot help more. Currently, the hospital bill is over $300,000 plus the medical bills at home are continuing to increase. The treatment process will last up to 3 years and we do not have enough money to take care of him since we are not allowed to work. We are asking for help, anything would become a great thing for us right now. Thank you.
