When researching the K1 process, I see a lot of people mentioning that different embassies tend to be tougher than others. In the tougher embassies, more and better evidence tends to be required for both the I-129F (proof of having met within the last two years) and the visa interview (proof of bona fide relationship).
How does the Montreal embassy slot into the spectrum of strictness? I would guess that it would be pretty lenient, just because I don't imagine there's much immigration fraud coming from Canada. But it would make me a lot more comfortable to hear from people who know first-hand what to expect.
My concern stems from the fact that, despite being with my girlfriend for 4 years and her driving across the border from Buffalo to visit me in Canada on weekly basis, we actually don't have much in the way of evidence for either the I-129F or the visa stage. Passports don't get stamped at the CAN/US border; we never go on vacation (so no hotels, entertainment tickets, etc.); I've always hated having pictures taken; we don't use Facebook; we never split bills when we pay for stuff; chat logs don't seem like good evidence of anything because there's no proof it's her on the other side of the screen; and so on.
There are certainly things I can seek out to create such concrete evidence, especially for the I-129F proof of meeting within 2 years. But how much evidence I need to create depends a lot on how strict I should expect the embassy to be.
So, for anyone who's gone through the K1 process in Canada (or somehow knows a lot about it), what sort of evidentiary standards should I be expecting to meet, roughly?
Thanks!
