The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
If marriage was entered into with intent to obtain immigration benefit, green card can be subsequently revoked by USCIS and the green card holder will be placed in removal proceedings in Immigration Court for marriage fraud.

There is no violation there.
