With more than 21 years of experience in the field of migration law and extensive knowledge of administrative law, Jeroen advises companies, individuals and (semi-)public authorities on issues of administrative and migration law. For instance, he assists companies with applications in the field of knowledge and labour migration and advises individuals on issues concerning (EU) family migration.


In his approach, he always tries to find the right solution to a legal conflict. "As a lawyer, I am always looking for the actual solution to the problem. I often look at the higher interest. The solution cannot always be achieved through a fight or dispute. I also try to make the client aware of this. Fighting for the principle sounds nice, but the price is often higher than the return."

In addition, Jeroen advises lawyers (law firms) and other professionals at home and abroad on complex migration law issues, for example on cross-border family law issues or international corporate structures. Where necessary, Jeroen litigates on the refusal or revocation of residence permits. Clients can also turn to Jeroen for assistance on various issues where interests clash with those of the government: fines, permits and subsidies.
