At only 30 Mason Ji has every credential that can be earned by a promising young lawyer.
Since 2020 Ji has practiced business litigation, corporate affairs and international sanctions law as an associate at Seattle-based Perkins Coie. His Chinese fluency was put to use helping clients with international trade and Bureau of Economic Analysis filings. It also proved useful in defending international investors in EB-5 investment fund disputes.

He is the founding member of Asian Americans for Justice and Equality and a columnist for United Chinese Americans since late 2021. Since August 2020 he has hosted Decoding America, a monthly radio show on Chinese Radio Seattle focused on civil rights and social action.
In 2013 he was appointed as a UN Adviser on the Republic of Seychelles Mission in which he participated in conferences on nuclear disarmament, climate change and human rights treaties. In the Obama administration Ji was a White House Ambassador for AAPI community needs.
While enrolled at Yale Ji traveled every weekend to New York City to attend UN meetings, becoming the youngest delegate to the General Assembly at age 18. He graduated summa cum laude in 2016 with a BA in global affairs and political science. As an undergrad he also studied at Cambridge in 2013 and Peking University in 2014. As a Rhodes Scholar in 2017 he earned an Oxford master’s in governance and diplomacy and in 2018, in public policy.
Ji earned his JD from Harvard in May 2021 and passed the Washington State Bar in September 2021.
