What about proving conjugal? I read about it and most applications are declined. What about going over to her country and get married there? Is there a waiting process after the family visa? What are some near-fool-proof options?
Conjugal is really for couple who because of circumstances beyond their control cannot get married. Like same sex couples in countries that do not allow those unions...or I believe Filipinos who cannot get divorced legally so they cannot marry again legally. Just examples. Since you can always go there and get married you do not have that barrier to marriage that would enable you to apply as conjugal.
You really should only follow one of these two paths...
1. She applies for a temp visa to Canada. IF she gets it...she comes here, you get married, and you apply to sponsor her here in country.
2. IF she doesn't get a temp visa to visit you here, then you start planning to get married there instead. You will need to learn what you need in the way of paperwork and what the process is to get married there. And then once married you need to sponsor her before she can come here. That process takes some work to collect all the paperwork and apply, do the medical, and then you wait while they process it for months.
You will likely have to follow option 2. But I have seen a couple instances where the woman got a temp visa as well...they are just less likely. Neither option is fool-proof since doing the paperwork does suck and requires detailed work...BUT the marriage route is the least fail-proof in any case.
