Late applications may be considered. But this is completely at the discretion of the admission committee. The response time for late applications may be delayed and late applications may not receive full consideration, especially for financial support.


  • Domestic student applications for Spring 2022 will be accepted until Decemeber 01, 2021.
  • There is no application fee for domestic applicants to the Ph.D. or M.S. programs.
  • GRE scores are normally required for international applicants.  But for Spring 2022, to accommodate for the disruptions caused by COVID19, GRE scores will be optional.  However, we recommend that you report official GRE scores using ETS if you have taken the exam.
  • For those who started an application prior to August 4, 2021: The 2021 application system is now discontinued.  Please do not apply using this old 2021 application link, as any information entered cannot be transferred to the new 2022 application link. Use the 2022 application link provided at the top of this webpage.



Your application requires all of the following:

  • A statement of purpose, describing your interests and motivation to pursue a graduate degree.
  • A resume or CV, describing your work experience, academic projects, and areas of expertise.
  • Three recommendation letters, from academia or industry. All recommendation letters should be submitted online. For Ph.D. applicants, we highly recommend that a majority of the letters be from academia.
  • Scanned transcripts, please make sure transcript scans are clear and legible or your application will not be reviewed.
  • Test scores:
    • GREs, please have ETS send your official GRE score to Stony Brook University (institution code: 2548). Normally, GREs are not required for domestic (US citizen or resident) applicants, but GREs are required for international applicants. For Spring 21 and Fall 21 applications, due to COVID19 disruptions, GRE scores will be optional for international applicants as well.
    • English Proficiency, if your native language is not English, please have ETS send your official TOEFL score to Stony Brook University (institution code: 2548). If you took IELTS instead of TOEFL, please provide a scan of your IELTS scorecard into your online application. For Spring'21 and Fall'21 admissions, we will accept Duolingo scores in lieu of TOEFL/IELTS.  See the Graduate Bulletin for more details. If you apply with Duolingo, an official Duolingo report must be sent to the Graduate School as described in the Graduate Bulletin; in addition, please provide a scan of your Duolingo score into your online application.

Do not send any official electronic/paper transcripts (or IELTS if applicable) until you receive a specific request. After a review process, students deemed admissible will be asked to have their official transcripts and official IELTS score (if applicable) sent to us by postal or official electronic delivery service. Please do not send us any official transcripts (or IELTS if applicable) until and unless you receive such a request, as paper documents tend to obstruct admissions processes and will likely delay the processing of your file.

Applicants to the CS graduate program are eligible for admission only if they do not already have a graduate degree of the same or higher level in Computer Science.

For additional information, please check our FAQ and the Graduate School's admission web pages.



All students admitted on a full-time basis to the Ph.D. program are offered attractive financial support in the form of teaching or research assistantships and fellowships, together with tuition and fee scholarships.
Students admitted to the M.S. program are generally not offered financial support at the time of admission, but upon arrival some M.S. students do find some form of teaching or research assistantships in the CS or another department on campus. Information regarding tuition, fees, and other costs can be found here


Admission to the graduate program requires a bachelor’s degree.  For MS, we prefer students with CS or related degrees.  Applicants with exceptional promise who lack CS preparation in one or more core areas may be admitted to the program, but will be required to take additional CS courses as specified in their offer letter.  For PhD, we mainly consider an applicant’s potential for first-class research, and expect the applicants to have sufficient academic preparation and strength to succeed in PhD qualifiers.
