International Welcome Desk

The ULB International Welcome Desk informs international students, members of academic staff recruited abroad, international researchers or visiting professors, and international postdoc or PhD candidates about the administrative steps to be undertaken before arrival at the ULB and the various formalities to be completed once in Belgium. 

On arrival in Belgium, you are warmly invited to pick up a welcome pack from our office at 52 Avenue Jeanne (Solbosch campus). We welcome you from Tuesday to Thursday from 10 am to 4 pm.

Please note that the International Welcome Desk can help you with questions relating to visas and residence permits. However, we are not in a position to speed up the application process with the Immigration Office or the town halls.

Registration of International Researchers

Single Permit Application for Non-UE Nationals

As of March 1, 2023, all foreign researchers, post-doctoral fellows and trainees (except doctoral students) from outside the European Union will need a single permit to enter and stay in Belgium for more than three months. Hosting agreements previously issued are no longer accepted as a document for obtaining a visa.

For help or information, please contact permisunique@ulb.be

Khaled al-Asaad Solidarity Fund

The Université libre de Bruxelles has created a Solidarity Fund in order to provide support for international researchers who no longer have the freedom to pursue their research in their home country, where they are threatened due to the content of their scientific work or to the opinions they have freely expressed.

You will find all the practical information to apply here.
