Why are the dossiers sent to China in groups?
This is done because it is easier for the agency and for CCAA to track the dossiers if they arrive in a group. In addition, this reduces the travel costs. This is because one guide/translator can work with up to ten or so families. This allows the costs for guide services are shared among the group rather than being paid for by just one family. Some agencies do not group families for either sending dossiers or for travel. This speeds up the process a little but means increased travel costs and requries the family to travel by themselves to China.
