Please be advised that, despite Corona and CoVid-19, Paderborn University is a Campus university and the standard modus of operation involves being present in Paderborn for your program.
For the upcoming summer term 2021, we are investigating options to enable remote participation for all students, local as well as international students. However, this cannot be fully decided at this time as this depends on how the Corona pandemic develops further.
For any questions and concerns with admission processes in general (including Visa issues etc.), please feel free to contact the International Office at https://www.uni-paderborn.de/en/studium/international-office/ ; for questions specific to the Computer Science program as such, please talk to study-cs(at)mail.uni-paderborn(dot)de / for Computer Engineering to one of the contact persons listed at https://cs.uni-paderborn.de/studium/studienangebot/computer-engineering.
For concrete questions concerning a particular class, it is advisable to directly contact the lecturer of that class herself/himself. You can find that information in PAUL's course catalog.
