I live in Vietnam and did a Bachelor of Business (Economics and Finance) from an Australian university, Vietnam campus. I am planning to apply for statistics for graduate study in the US. I have always been in math-specialization classes since I was in grade 3 and I attended the best highschool in my country. However, when choosing undergraduate major, I was not fully advised and chose finance, the hottest career in my country. My family's financial condition back then was also not so great for me to think about studying abroad. However, now my family's financial capacity is much better and I also realize the opportunity in statistics in the US.
Really appreciate any inputs about how I should present my case so that the admission committee can realize my ability and passion for statistics, especially from someone who has done this before (change major from undergraduate to graduate)
