Thank you so much for the link. So I think there is still a very little chance to get approved.
I have few questions about visiting visa.
Can I apply through GC key for visiting visa (spousal application linked to GC key already)
Can I tell CIC in the letter of invitation that spousal application is in process? (I guess I must?)
My wife already did her medical for spousal sponsorship. So how will I provide that medical results for her visiting visa?
I am really sorry if my questions are dumb.
No, your questions are not dumb LOL. They are pertinent questions.
To answer your questions:
1. Yes
2. Yes. Even if you dodn't tell IRCC, they would know about her PR application. But, you must mention it.
3. Medicals are not required for the TRV/visitor visa. Her current medicals are already on the system.
Do ensure that your wife demonstrates some strong ties to return home to: Employment/business + property ownership or a lease agreement in her name + good financial situation without borrowing from anyone, etc
