U.S citizen
As a U.S. citizen, you would divorce your immigrant husband in exactly the same way that you would divorce a spouse if he was a citizen. I am not sure from your question, but if your husband's green card status is still pending, then divorcing him during the process will affect this application. If your husband was granted a conditional green card, his permanent residence privileges may be revoked if he is divorced within two years from the date this status was granted.
It may indeed, but that's no reason not to get divorced in this case. See a lawyer to see what your options are.
