... in response to k1 visa question to canada from US, posted by mudd on Jul 11, 2003Mudd,
The K-1 visa is a one-entry type of visa. When she enters the US the first time, she is already making use of this one-entry "prividlege". If she goes to Canada (even if she gets a visa to enter Canada) she will be trying to enter the US for the second time and if they found it out, she could be denied to re-enter the country.
On the other hand, you could get lucky and get away with it.
Some people, when asked if they are American citizens just answer, yes and that's it, but if they ask you for papers they will discover the lie.
I have been twice to Canada (as a U.S legal resident, I don't need a visa to enter Canada). When returning to the US, my husband was asked if we both were Americans, he answered he was, but that I was a legal resident and they asked to see my green card and Passport.
I don't think you guys will have too much trouble entering Canada (I have never been asked for papers), but you could encouter problems when you want to reenter the U.S.
But, I know people who got away with it. Of course, this happened before 9/11.
