I work in IT and I did search for forums and I found other ones which were useless so I suppose I could have searched harder and stumbled across this one but I really didn't think it would be this difficult. It would be similar to researching how to do anything you think should be simple only to find out later the game is rigged.
You have a much different perspective being from the Philippines than I do being from Canada. I can travel to over 160 countries without a visa so it's not something most Canadians have any familiarity with unless they travel to very exotic destinations.
I find it so bizarre because my country lets in hundreds of thousands of immigrants and refugees each year and why make such a big deal over one person with a boyfriend who says he'll pay for her way. If something happened and I didn't pay they could come after me for the money, that would seem more fair. Their refusals would more sense if she applied on her own without knowing anyone in Canada.
It's not easy being refused 5 times in as many months. That causes a good deal of frustration and stress besides the change in plans.... all along hoping that at least one TRV application would get successful.
Maybe a few months later when you step back from these five TRV applications, you would be able to see why we believe your girlfriend had a weak application for each of the times that she had applied. I had given a one-to-one analysis of why her applications were weak in my first post in this thread.
Perhaps, if you had sought advice from this forum before applying in quick succession, you would not be in the situation that you are currently in. Well, that's hindsight which doesn't help now.
IMO, we've come across TRV applicants from the Philippines whose personal/professional situations were much more challenging than your girlfriend's. With a complete overhaul in their paperwork + understanding how to address the concerns of the visa officer, they were successful in getting TRVs.
Your current situation does not allow for another TRV application for several months. That's the hard truth. Maybe if she establishes strong ties before she applies next summer(?) with stronger evidence, she could be issued a TRV. It is possible. Or else you may want to consider the spousal PR route
