My wife called them (Gemeide's staff) and answer is; yes I can BUT its quite a lenthy and troublesome process!

I got to prove them that I can bear all the cost for my parents living here in Switzerland. Plus, the reason for reunification must be really impressive!!! I hope all will go well.

About the college admission for my sister, I'm talking about admitting in Bachelor degree (commerce) College with English medium. More info about these will highly appreciated.
