I’ve volunteered in this area for decades (I’m sure one could do a search to see my many posts on this topic). Reuniting families quickly is critically important, but more important that it is done right. My organization isn’t helping with this aspect, but I am writing letters supporting DNA testing for this purpose. In my own experience, human trafficking, particularly of children is a much more widespread problem than many realize.
CRD, have you considered working with general immigrant groups - there is very great need all the time, and as it was mentioned upthread many of the immigrants speak indigenous languages that aren’t commonly translated.
I applaud your willingness to help. There is so much to be done.
