This makes sense. I am an immigrant my self, had a good job and life in my country of origin but the US showed interest to bring me in and allow me to maximize my potential.
My direct relatives live happily where we were all born. They have never showed interest in coming to live here and I have never pushed the subject ... that doesn’t mean we love each others less.
I believe anyone who comes wishing to live in our community need to follow the same rules, if more family members wish to join they can apply and go through the same process ... more than likely they’ll get approved, having a good precedent set by the initial family member.
