Hi @MIKE 130,
From my reading of the law on Kindergeld, with the resident permit 19d you are entitled to it. The law only refers to the residence status of the parent and does not make reference to the child having to have a particular type of residence permit or any at all. Apply for it with your local Familienkasse. If the Familienkasse make any issue of the fact that your children do not have residence permits, request that they provide you with the legal basis for questioning this.
