Dear @maribel999,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
Generally speaking, parents can receive Kindergeld (child benefit) for children between 18 and 25y. if they are in their first "Ausbildung" (incl.), school or study programme as well as in their second "Ausbildung"/school/study programme and work for up to 20h/week. This website explanis the conditions quite well.
If I remember correctly, however, you and your parents are still in the asylum procedure, right?
Unfortunately, asylum seekers (pending procedure) and rejected asylum seekers (with Duldung) are not eligible for Kindergeld.
I am sorry that I can not give you more positive news but please don't hesitate to get back to us with any further questions.
All the best,
Meike
