Hi
But PR s have the right to sponsor their spouses
No, not in the OP case, he includes his spouse in his application as a dependent, which is entirely different from a sponsorship. If he is approved, she will be issued a visa at the same time. As he is working in a skilled occupation with a work permit, his spouse could apply for TRV and OWP now. There is no guarantee that it would be issued.
