As in the title.
If the US citizen spouse is angry about something with their overseas spouse who is about to immigrate to the US on a marriage-based spousal visa (the one where he'll get a marriage-based green card), so much so that they want to "cancel" the visa, do they have the power or authority to do so? Such as threatening to "call immigration". As far as I know, there is no true "calling immigration".
Or, if they can't stop the spouse from legally entering on that visa, can they somehow stop the green card from being issued? Or anything else that they can sabotage?
