Elderly parents as dependents

I'm sure they can apply to be dependents through your sister. But she may have to write a letter of support.  I think they can apply for it with the Prime Minister's Office.

How can you be so sure? what is your level of certainty?
The sister became citizen through marriage and thus won't have any right for such endeavours.

If the sister is a Mauritian citizen, whether she is naturalized or not has no bearing on the situation. In almost every country you can apply to have your parents live with you as dependents, Mauritius would not be different. What i'm not sure about is what procedure has to be done.

As i said, check with the Prime Minister's office, they can tell you for sure.
