http://www.visajourney.com/forums/ super site about relationship visas.
k1 is for a fiance, so have a good read on that forum. stickies at the top explain it
Sorry, she just can't get citizinship, doesnt work that way,there is a process to go
k1 = fiance (not already married) other relationship visas are the k3 and Cr-1, which the person is already married.
differences:
http://www.visajourney.com/forums/index ... ge=comparek1 tends to be the fastest, but as u can see from the above link, there are negatives. each has to consider their own personal situation.
And I belive she can collect Cdn maternity benefits in the USA, but she may have to give birth in Canada to collect it. Not sure about the details, something to look into though, I havent had my morning coffee yet, so pretty dopey,lol
But read the stickies and you should be fine. VJ is a pretty complete forum with regards to relationship visas. Even examples of filled out forms (at top where it says example forms)
k1 takes approx 6-8 months, interview in either Montreal or Vancouver, depends where she lives in Canada. USA spouse does NOT have to attend. best of luck
