Proof that marriage in the US without K-1 visa is OK

[KLS2010 30]

Ok...I did a quick search and this is what I found. Now, I know that your fiancee is Canadian, and this is referring to B2 visitors, but I figure if it's ok for them, then I can't see why it would be any different for Canadians who don't require visas in the first place.

9 FAM 41.31 N14 VISITORS UNDER SPECIAL CIRCUMSTANCES

(CT:VISA-1777; 11-29-2011)

The following classes of aliens may be classified B-2 visitors under the following special circumstances.

9 FAM 41.31 N14.1 Alien Fiancé(e)s

9 FAM 41.31 N14.1-1 Fiancé(e) of U.S. Citizens or Permanent Resident Aliens

(CT:VISA-798; 03-23-2006)

An alien proceeding to the United States to marry a U.S. citizen is classifiable K-1 as a nonimmigrant under INA 101(a)(15)(K). (See 22 CFR 41.81.) The fiancé(e) of a U.S. citizen or lawful permanent resident (LPR) may, however, be classified as a B-2 visitor if you are satisfied that the fiancé(e) intends to return to a residence abroad soon after the marriage. A B-2 visa may also be issued to an alien coming to the United States:

(1) Simply to meet the family of his or her fiancé; U.S. Department of State Foreign Affairs Manual Volume 9 - Visas 9 FAM 41.31 Notes Page 25 of 32

(2) To become engaged;

(3) To make arrangements for the wedding; or

(4) To renew a relationship with the prospective spouse.

(Note: The highlighted section in red was the main part I wanted to show, but put the rest in to show the context )

This came from the Department of State's Foreign Affairs Manual. Here's the link.
