I have just received my unconditional green card in the mail. I am in ongoing argument with my wife(USC) over my mother-in-law because of something my mother-in-law has done to me but my wife is taking her mothers side. During this argument my wife has threatned to leave me and file for a divorce and she has promised me that she will do something very 'evil'. My mother-in-law had signed the affadavit of support back when we filed all the immigration papers. I am not taking this serious because I think she is just saying that because she is upset with me. But if she or I do file for a divorce will it have any negative consequences on the immigration process?
