After graduating from Lycée Jean-Jacques Rousseau in Saigon, Phong attended a university year at the École Polytechnique Fédérale, Lausanne, Switzerland and then went to the United States as an undergraduate and then a graduate student at Princeton University. From 1975 to 1977, he was an L. E. Dickson instructor at the University of Chicago.
In 1977, he defended his dissertation entitled "On Hölder and Lp Estimates for the Conjugate Partial Equation on Strongly Pseudo-Convex Domains" under the direction of Elias Stein.
