May I apply for the PhD by e-mail?
Unfortunately, not. While you may be able to email your documents when you are looking for a supervisor, if you are applying for a place on the individual doctorate or structural PhD, you will need to submit the original Supervision Agreement (please note that there is a waiting period for obtaining such an agreement). Also, your MA and BA certificates (maestría, licenciatura or equivalent) must be either originals or certified copies.
