Super-visa for parents at the same time

[muralim]

Hi There,
I am planning to apply for super-visa for my parents who are living in my home country now. But I am not sure whether I should apply for both of them at the same time or father and mother one after the another. My parents have 4 kids and all of us are abroad now. So my concern is if I apply for both of them at the same time, the visa officer might think that they do not have enough reason to go back. So my questions are:
1. Should I apply for both of them at the same time or mother first and father then?
2. If I apply for both of them, is there any possibility that only one of them get approved?

Thanks in-advance.

As long as they are eligible, there should be no difference in applying both at the same time or separate.

Of course, I did. But one of the eleigibility criteria is strong ties to back home. In my parent's case, if both of them apply for Canada super-visa, they do not have enough ties back to home country except financial assets.
