Navigate to Harvard's Office of Transfer Admissions website (admissions.college.harvard.edu/apply/transfer/index.html) to find out when each part of your application must be submitted.
Fill out the Common Application (commonapp.org) or the Universal Transfer Application (universalcollegeapp.com) online, making sure to fill in the Harvard Transfer Application Supplement. In both instances, you will have to register before you fill out the application. Click on the "Register" option on the home pages of these websites to do so. You will be asked basic information, such as your full name, your address and your email address. You'll also be asked to select a username and password so you can sign in to the online application.
Submit a payment of $75 to Harvard. You will be able to do this electronically from the online transfer application you completed in step two.
Submit your official transcripts and test scores from your secondary school to Harvard's Office of Transfer Admissions. Contact your secondary school to have the transcripts sent to Harvard. Contact the American College Testing Program to have your testing results send to Harvard's Office of Undergraduate Admissions.
Submit your official college transcripts to Harvard's Office of Transfer Admissions. Your current college's registrar will be able to do this for you if you ask, but there will likely be a fee associated with this.
Submit two letters of recommendation to Harvard's Office of Transfer Admissions from faculty members or teaching assistants who are familiar with your work. The letters should stipulate why the professor believes Harvard will be a good fit for you.
Ask the dean or administrative officer of your current program to submit a university official report to Harvard's Office of Transfer Admissions.
Wait for Harvard to contact you via mail whether or not you have been admitted as a transfer student.
