Yes, I knew about the "probationary period" etc.

But the unqualified "no leverage" of the OP seemed to imply at least to me that they thought that the green card would be taken away in a divorce irrespective of number of years of marriage (it doesn't after two years unless you got into a fraudulent marriage).

And I do not think the GP suggested getting a sham marriage. Yes, if you really enter into a sham marriage then the "wife" will have lots of leverage over you.
