What is the Verpflichtungserklärung?
If someone invites you to Germany for a short time, they can submit a declaration of commitment for you. This is called Verpflichtungserklärung. This is especially useful if you cannot pay for the cost of your stay in Germany by yourself. The declaration of commitment / formal obligation letter is generally recognised by German missions abroad for up to 6 months after it has been issued.
