I am not trying to give you a hard time here, but it strikes me that Lebanon being in economic crisis and the passing of your grandmother do not really come across as cogent and compelling reasons for not going there to spend time with your wife.
As for Covid "running rampant", I suppose that still applies today. I know of a few people here in my province of BC to get the virus in this past month. Was Lebanon on a list of places to which the Canadian government has warned against travel until now?
You have not answered
@scylla's direct question about how much time you have spent with your spouse, but the answer is found in another thread where you said you have made a single trip of 2 weeks' duration, during which you were married. That's it. I am sure scylla is right when she says that's a weak profile. She is not making this stuff up, but simply relating to you what her years of observing these things tells her. She is right too, that no MP is going to change the IRCC's view. If that could happen, the IRCC might just as well turn the final decision over to the MP.
Looking at our own case, my wife and I met in November 2019 and I spent a month with her in her country. We applied for a TRV in January 2020, just ahead of Covid, and were denied in February, just weeks before Covid became a global issue. Her country was locked down until February 2022. No foreign visitors allowed in. It re-opened on Feb. 10/22 and I arrived there on Feb. 18. I stayed for 2 months and we married in that time. We also applied again for a TRV while I was there. Denied again.
I went to see her again, in November 2022, and stayed for 4 months, during which time we submitted her PR application. We were unable to submit sooner due to waiting for PSA marriage certificate and making a trip to Dubai in November 2022 to procure a PCC, after trying since June to get it without having to go there. We applied for TRV yet again, just before I left, thinking our application was 4 months along and we had achieved SA, medical done, etc., so that would help. Still denied.
Why am I telling you this? Because we fully expect her PR application to be denied, although we think we should have a strong case. Just like you do. We have 2 strikes against us. First, we have 3 TRV denials. There's general agreement on this forum that 3+ denials substantially weakens a PR application. We have, in effect, been told 3 times that we are lying when we say she'll return to her country. We so are now viewed with great suspicion and she is perceived as "desperate" to come to Canada. Strike 2 is the fact that a am more than 20 years older. That makes VOs see red. Pisses 'em off. Seems immoral, improper, unseemly, etc. Can an MP change that view? I doubt it.
We will see my wife's application through to the end. We are unlikely to appeal a denial. Probably a waste of time. I'll move there. I lived there before and can do so again. It has many attractions. Let me ask: if your wife's application is denied, will you move to Lebanon? I kinda' see that as the acid test. If you can't or won't, then is it a real marriage? No one is guaranteed a PR visa to Canada. Who would say: You can be my wife, conditional upon you moving to Canada and, if you can't or won't, that's the end of the marriage?
