Ah, but here's a big "what if?" for you.... What if a fiancee or recent wife here on a K-1 goes to Alaska by automobile?
Not sure if you are posing a serious question or not.
If your wife is arriving here (Alaska) on a K-1 by automobile, the presumably she has already gained entry into Canada through some mechanism. Therefore, when she arrives at the Alaska border, she has a normal K-1 POE there. Rather like a Canadian would I guess.
If you're saying that wife has already arrived somewhere else in the U.S. on a K-1, and you got married, and have yet to receive a PR card, it is unlikely she will be permitted into Canada, therefore will never make it to the Alaska border. However, if she DOES, then will be denied entry into Alaska since she has no valid visa. A passport is not required for U.S. citizens and permanent residents, or Canadian citizens/residents for land travel, but one still has to demonstrate the right to enter the country. Russian nationals demonstrate this right with a passport and a visa, even if coming in by land.
In the above situation, but she has an AP, well, then she can enter without a visa, and probably without a passport, as long as she can prove her identity (presumably with a driver's license).
If she has a PR card, then she does not need a visa, or a passport. The PR card is enough to demonstrate her right to enter the country.
In short, there is really no difference entering the U.S. by auto just because it is Alaska. It's the same as entering the U.S. by auto through any other state.
I am guessing you have in mind the whole, "we don't need a passport for re-entry for land crossings" stuff, but that only applies to people who can otherwise demonstrate their right to enter the country.
As for the ferry:
QUOTE(AMHS)
If you live in the U.S. and will be traveling through Canada in connection with your ferry trip, you will not need a passport or visa. Native-born U.S. citizens (adults, children and infants) should carry a birth certificate which proves their citizenship. Driver's licenses are no longer being accepted as proof of citizenship. U.S. residents who are not citizens should carry their Alien Registration Receipt Card. Canada Customs officials will require travelers to show proof of sufficient funds for the trip.
Cheers!
