Thanks The_Specialist for information, I am aware of that....

There are too many things which makes your life hell on Family visit visa.

1. In Family visit visa you need to arrange everything, your PRO or company representative wont support.

2. If you family comes, then within 72 hours you need to take them for Medical test.

3. Once the medical test done start preparing for visa extension.

The point is while doing your job from sunday to thursday, it is very difficult to do all the these activities....My employer will take care everything in case of family residence visa...

It is a matter of time which we are not getting .....

Thanks,
Umair
