Proof of sponsorship and/or lodging provision
This proof is often needed if you are visited by someone from abroad. You then act as guarantor for any expenses or debts incurred by the visitor in the Netherlands.
In the proof of sponsorship and/or lodging you explain why you invited the person. For example, for vacation. This allows this person to show what he/she is coming to the Netherlands for. This is necessary for a visa.
