Intending to enroll himself at St Bartholomew's Hospital to pursue postgraduate study in medicine, Bidhan set sail to England in February 1909 with only 1200. However, the Dean of St. Bartholomew's Hospital was reluctant to accept an Asian student and rejected Bidhan's application. Dr. Roy did not lose heart but kept submitting his application again and again till the Dean, after 30 admission requests, admitted Bidhan to the college. Bidhan completed his postgraduation in just two years and three months, and in May 1911 accomplished the rare feat of becoming a member of the Royal College of Physicians and a fellow of the Royal College of Surgeons simultaneously. He returned home from England in 1911.
