In this case, CR-1 would have been a much smarter choice.
If you need to travel, I wouldn't rely on advanced parole. There is no guaranteed timeline, and it is not a substitute for a green card.
That isn't it at all. US citizens have been scammed for green cards by people from third-world and developing countries. It pays to be vigilant whenever there is a large difference in equity in a relationship. Many of these marriages would never happen if living in the US was off the table....
So does filing a fiance visa petition without being completely sure. After all, it does require intent to marry. It is not a "try it out and see" type of deal.
It was intended as a way to explain why it might take longer. And it is true- many of the reasons for delays in the AOS process are not present in consular processing. OP made that choice, it’s a trade-off.
But was yours an entry on a visa? Instead of petitioning her, she entered the US and is adjusting status, which is a convenient way to bypass the long queue in Montreal.
It’s just bizarre to even bring it to the attention of the airline/your country’s passport control.
I agree with Crazy Cat, for other people reading this: do not do this.
So she deliberately omitted your name on the form where it asks who you know/who you're visiting in the US?
Personally, I don't think that's smart. Such lies have come back to haunt people later on when pursuing other visas.
It also is not a great idea for her to lie at the border when they ask who she's visiting.
