Hi there
We have the same problem but two girls aged 23 and 22 both working so classed as independant and a boy of 16 in education which means he can come on our visa. We hesitated in sending off our visa because of this but have now sent it as there is no way they can come as dependants whatever way you look at it. We are going to do: one of them wants to study so will look at the study visa and then try and get her to do a trade on the MODL list and apply for
PR after, a long and drawn out process but we don't know what else to do and the other one wants to do a WHV and do some sort of fruit picking for 3 months, which then gives her 2 years there. Don't know what we will do after that but if it comes to it I suppose we would have to come back if they couldn't stay.
It is really worrying and I wish there was an answer for us but there is no way they could go back to full time studies here as they have financial commitments.
If you are able to I would definitely send them back to study and put them on your application.
