Flight ticket to University

My name is Mirian George. I’m Tanzanian and I attended high school at UWCRCN in Norway where I studied International Baccalaureate Diploma.
        I was recently given a full scholarship at Earlham College where I plan to take undergraduate studies in Mathematics and Economics. The college offered me a really good financial package which will cover my tuition, food and accommodation.
       Despite the financial package, I still have to cover costs of flights and visa and that poses a financial hardship to my guardian (aunt) and I.
        I will be starting school this fall but I cannot proceed with visa processes since I do not have enough money for that. Also, without a flight ticket, I won't be able to start my studies.
      Please help me to support my education by contributing whatever little you can give.
      Thank you for your time and support. It’s greatly appreciated.
