One appointment or multiple ones?

[SaveThePlanet]

I want to sponsor my mother, sister and nephew(6yr old) for visitor visa for the first time. Is it better to take one interview slot for all three as a family or is it better to take it one day for my mother and another for sister and nephew seperately? My concern is that if they all three go toegether it might appear to the consuate officer that they may not return. Also, another possibility is sending them to different consultes. What is the best approach?

I don't think it matters as they look at each person independently anyway.

Take one for mother another for rest.
