Now an active GS alumni leader, Cao gives back through mentorship while championing strategic preparation, technical excellence, and creative risk-taking as pathways for international students to build meaningful careers in America.
What is your GS story in one sentence?
GS gave me the opportunity of a lifetime and the journey refined me through knowledge and discipline, shaping me into a builder who turns ideas into real ventures.
What was it like moving from China to the U.S. and trying to navigate school and work in a new country?
Moving to the U.S. felt like stepping into the unknown and rebuilding my life from the ground up. Every decision carried weight because I was entirely on my own—navigating academics, finances, and immigration with no safety net. The learning curve was steep: balancing school, cultural adjustment, and visa logistics, all while trying to build a future I could be proud of. The real turning point came when I founded Ms. Dan’s Academy and my firm Mandarin Staffing immediately after graduation during COVID-19. I created these businesses out of necessity, transforming uncertainty into action and building opportunities where none existed. There were many moments when I questioned whether my efforts would ever pay off, but I kept doing the only thing I could control—trying, failing, adjusting, and moving forward. Those early years taught me how to build a life in America one deliberate, resilient step at a time.
How do you continue to stay involved with Columbia after graduating?
After moving to Miami, where I initially had no network, Columbia became my anchor. I drove long distances to attend events, meet alumni, and stay connected to the community. Over time, this consistency allowed me to contribute more meaningfully, eventually joining the Columbia GS Alumni Association Board. Through this work, I’ve mentored students, supported new international alumni, and helped strengthen the community that once carried me. The personal connections originating from Columbia became the foundation of my American experience. The friendships I formed there truly became my American family.
What advice would you give to a new international student looking to start a career in finance in the U.S.?
First, understand the logistics. Visa status matters, and some firms simply don’t sponsor. Research companies’ H-1B and green card sponsorship histories and focus on firms with a consistent record of supporting international talent. Second, master the recruiting cycle. Many students miss opportunities not because they lack ability, but because they don’t understand timing. I received my full-time offer before beginning graduate school because I entered the right cycle at the right moment. Third, build exceptional technical skills. Finance is evolving rapidly with AI and data analytics. Strong technical fundamentals make you competitive and help justify an H-1B sponsorship, which exists precisely for specialized expertise. Finally, leverage your creativity and school resources. The U.S. offers unparalleled access to risk capital—if you have good ideas, people will invest in you. Use this golden time to explore, experiment, and grow. America is truly a land of opportunity, so give yourself the space to dream and build.
What is a standout memory or lesson from your time at GS?
My standout memories are the simple, late-night moments with my GS friends in Butler Library—studying, laughing, and sharing life’s worries together. Those sleepless nights taught me that the people you surround yourself with are the true secret sauce to your success.
