Why not? I'm Vietnamese, as is my wife. We both share same cultural views, have same education, speak same languages, only a 3 year difference, and most importantly, she's not interested in coming to Canada, she's only come there to be with me, because I wanted her to be there. She lived in the US for a long time, but returned home because she found it difficult to live over there (then again, she was in New York). Expenses were too high, and her parents couldn't afford to finance her education, and she can't work because she's on a student visa. When we were together, she kept insisting if I can go live there in Vietnam, but I have a great career here in Canada and I can support her extremely well. Right now she makes 5x the average Vietnamese salary, and she could support me if I was there, but I told her I want to be the one take care of her, thus wanting her to come Canada. And if my wife's PR is refused, you won't see me crying and losing sleep over it, the first thing I'll do is appeal it, and if the appeal fails, only then will I start to pack my bags and go live in Vietnam with her, and I'm more than willing to do it. At least the weather is nicer over there
We married because we love each other, we didn't marry so that she can come to Canada, therefore, it really doesn't bother us if the PR application is successful or not.
I didn't rush to propose to my wife, and I certainly didn't rush to get married either (we married one year after the proposal). I also brought my entire family from Canada to Vietnam for the wedding (they all paid their own flight tickets to come, took time off work, didn't give any excuses like "Cannot take time off work for the most important day of my child's life, due to work"). My sister, 2 brothers, stepdad, mother (who cannot walk and needs a wheelchair), grandma, my stepdad's sister, and 2 family friends, all came to my wedding, spent their own money, took time off work to fly all the way to Vietnam for my wedding. Mind you, my siblings are all under 25, and they're just starting out their careers, their income is relatively modest, yet they were able to make it to my wedding. My wife's entire family and relatives, some coming from Australia and France, all came to our wedding too. We didn't choose to rush our wedding to get the PR done quickly like some people, we even moved our wedding date to a later month so that my Canadian family would be able to attend. During the year before our wedding, I even worked 2 jobs to save up for the wedding and be able to stay in VN for 2 months. I had to pay a $1200/month mortgage + expenses for 2 months, even though I wasn't living in my house during those times.
I wouldn't have dated her if she was much older or much younger than me (I was 27 when my wife and I were together). Too old means the woman is further away from child bearing age, and I want to have a family. Also too old would mean she would have more life experience than me, and would try to boss me around, tell me what to do in life, and I don't like that. Too young means the girl does not have enough life experience, does not know what love means, does not know how to plan her future, likely doesn't take life seriously enough, and I don't want that either. Having someone who's closer to my age means we both have similar life experiences and can learn and grow in the same way. Having someone who has the same culture, language, education, means I feel more compatible to her, and I can interact with her at my own level
I know my situation doesn't apply to everyone, and my situation maybe makes me less likely to have my case scrutinized by CIC compared to someone with more red flags, but honestly, like I said before, if a couple has a genuine relationship, the sponsored spouse should be allowed into the country no matter what, and even if you guys have age difference, as long as the rest of your application is solid, you WILL get PR. If you have more red flags, well then you just have a lot more work to do.
And sorry if you felt my last post was indicative of my views, but its really not. I'm just trying to show you what CIC may think. There's a reason they consider age differences red flags, as well as education differences and what not.
