Before offering a brief explanation about work permits and visas, it is important to state that you absolutely should not initiate certain procedures on your own initiative, since this could cause significant delays!
If you come to work at the UMC Utrecht, you may have to deal with immigration procedures. Some will have to be arranged before you arrive in the Netherlands, while others can take place afterwards.
When you arrive in the Netherlands, you must possess a travel visa or a work permit. After arrival, you must have a residence permit or register with the municipal registration office.
Which procedure applies to you depends on your nationality, the purpose of your stay and how long you want to stay in the Netherlands.
Once you are hired for a position at the UMC Utrecht, the HR department will inform you of all the procedures that are relevant for you.
