Edyssy Support Center

In 2014 these were the thirteen questions applicants asked most, pinned to the top of the help desk (the story of Edyssy explains where it came from). The original replies did not survive. We wrote new ones from the professor’s side of the desk, with current rules and plenty of detail.

The old help desk filed every question under one of these headings. Some now hold several answers, some hold one, and a couple are covered by tools elsewhere on the site.

About the Support Center

Why are these 13 questions and not others?
They are the questions the 2014 Support Center pinned as its top 13, preserved in the web archive. The original replies were lost, so each answer here is new, but the questions and their categories are the ones real applicants asked.
Can I ask a new question?
Not through the site; there is no account system or comment form anymore. Most follow-up questions are already covered in the question-and-answer section at the end of each article.
Which answer should I read first?
If you have not contacted any professors yet, start with how to contact professors and the sample email. If you already have offers, go to the comparison pages. If you are deciding whether to apply at all, read the CS PhD versus job piece.
How current are the rules quoted in the answers?
They were checked against official sources in November 2026, including the Council of Graduate Schools April 15 Resolution, ETS test policies and federal rules for F-1 students. Policies change, so confirm deadlines on program and agency pages before relying on them.
