男方提出離婚,要求女方自願放棄任何財產,否則撤銷其已申請的綠卡?
This is classic extortion, a criminal offense in every state of this country. A complete offense, if convicted, means 3-4 prison time. An attempt will also put this guy in jail for a year. There are civil fines as well, normally in the tens of thousands of dollars. Talk to the police and try to protect yourself.
