Hey guys, its me again..
While I am still making my decision, another industry person mentioned that, I can abandon the appeal, and appply for Supervisa,
once she is here, I can apply for a new H & C ground based on both siblings are here and that she truly requires to be taken care by the family..
Appreciate if you shed any light on this..and wishing ya all a great day!
I doubt this will work. You can only apply for a supervisa if your parents voluntarily renounce their PR. But once it's voluntarily renounced, I don't see how they could put in an application to basically reinstate PR again. Have never seen a case like this on this forum. But will let others comment.
