Prepare your stay

As an international student, you will need to take care of a number of practical matters both before and after arriving in the Netherlands. Check this website to find out about the steps you need take and appointments you need to make.

Warm welcome service

On certain dates shortly before the start of each semester, Leiden University organises a Warm Welcome Service for newly-arriving international students. This includes assistance in finding your way from the airport to your accommodation, as well as advice on the formalities you need to take care of after arrival. More information will be available soon on the warm welcome service page. If you have any questions about the Warm Welcome Service, please send a mail to: arrival@leidenuniv.nl

We are preparing to provide (all) our teaching on campus as of the start of the new academic year, without any restrictions. Make sure that you start early applying for housing or finding housing yourself. On the housing page you can find more information about arranging accommodation.


In the Prospectus (E-Guide) you will find all detailed information about the courses you will follow, including the learning objectives, assessment method and literature per subject. You will also find the registration codes for courses and exams here.


Regardless of the status of your application (perhaps one or more conditions still need to be met), this e-mail already provides some general information about the start of the academic year. 
In case your registration is not yet complete, please send in the required documents. We recommend that you complete your registration as soon as possible. More information can be found here. If you experience any difficulties or have questions during the process, feel free to reach out to the Student Affairs Front Office or send an e-mail to: bacheloradmission@sea.leidenuniv.nl. Not being registered means that you cannot follow this programme.


You can order your study books at a discount through the study association De Leidse Flesch. During the summer holidays you will receive an information letter from De Leidsche Flesch after your registration at the university. If you become a member of De Leidsche Flesch you will receive an e-mail with more information.

My Study Map

Students who are starting their studies for the first time are registered by the student administration for the courses in the first semester of the program for which they have registered via Studielink. This registration takes place in the last week of August and is repeated at the end of the first week of September. This doesn’t include the exam/retake, which still needs to be confirmed by the student; the students receive notifications about this from MyStudyMap.
An overview of all first-year courses can be found in the E-Guide.
Or check our Q&A.

We expect students to bring a regular laptop running Linux or Windows. MacOS may in most cases also suffice, but less support might be available. There are no strict hardware requirements. However, for most of the courses we advise a laptop with sufficient (8GB+) memory, a modern CPU (medium range, not necessarily high end), and modern GPU (medium range, if possible CUDA-capable, definitely not high end).

Very intensive computation does not need to be performed on these laptops, but would take place on university servers.
