He then started to work at the University at Buffalo and retained his British citizenship after moving to the United States in the 1950s. In 1958, he moved to the University of Virginia. Coase settled at the University of Chicago in 1964 and became the co-editor of the "Journal of Law and Economics" with Aaron Director. He was also for a time a trustee of the Philadelphia Society.
