I and my younger sister are from Asian country and she studies in China. She would like to visit her friend (same nationality as us) who is studying in Germany, during holidays. I want to sponsor her during her visit but I am neither the host nor a German resident. Can I write a Letter of Commitment for her visa application and what kind of documents should I provide?
You should understand what sponsorship means in this context.
- You cannot make sure that your sister will leave the Schengen area, so promises by you will not help in this regard.
- Your sister will have to explain how she will afford the trip. If her explanation is that you will pay, she must explain why you would pay, and you must explain that you can afford her trip.
