At present, the employment of undergraduate medical international students in their specialties has seen leapfrog development, and senior medical students are facing serious problems and challenges in employment. In order to improve the employment willingness of senior medical students, the discussion of the influencing factors of the employment choice of undergraduate medical international students is proposed. Firstly, the undergraduate medical international students from several colleges and universities in a certain province were taken as the research object, and the demographic situation of graduates was analyzed to analyze the current situation of employment guidance. Then, we analyze the influence mechanism of different factors on the employment choice of international medical undergraduates from three aspects: students' intrinsic factors, policy factors, and employment guidance factors of colleges and universities. Finally, the above factors are combined to propose specific measures to improve the employment willingness of international medical undergraduates, including the government's broadening of employment channels for international students, the optimization of the focus of employment guidance in universities, and the need for graduates to improve their own job-seeking ability. The aim is to solve the contradiction between supply and demand in the employment of senior medical students and to improve the employment prospects of international medical undergraduates.
