Hey, they could just get married in Columbia and then come here as 'family!' Oh wait, Columbia doesn't offer gay marriage either. Oh well, I guess he will have to find a Canadian to gay marry.
Don't laugh, one of the objectives of homosexuals marrying in canada was to enter the USA with a "spousal visa". This is currently under litigation in the federal courts. Because the 1996 DMA stands, there are no spouse visas for sodomites.
