For declarations of commitment for visiting purposes (no longer than 90 days), you need to prove your financial capacity as a host; this is usually based on your income.
The deciding factor is that your net income must allow for a minimum attachable amount of 281,50€ per adult guest or 140,75€ per minor guest. You can look up the amount of income required in this garnishment table (starting on p. 10). It depends on how many people are legally dependent on you and how many guests you would like to invite.
As of: April 2024, possible changes and more information can be found on the website of the city of Bochum.
Example: If you have a legally dependent spouse and a legally dependent child and you want to invite one adult as well as one minor guest, you have a maintenance obligation for 2 people and need an attachable amount of at least 422,25€ per month. Therefore, you need a monthly net income of at least 3.280€.
Please note: It is not possible for scholarship holders to submit a declaration of commitment!
