Having sex with a store employee is not a crime or even a reason to be fired, unless you can prove it was not consensual. If he was a such sexual predator don't you think there would be more incidents and complaints from people besides his ex wife? If his line of work is fake don't you think people can catch him for wrong doings with proof?
What do you want from him, give up his work get his GC back and come back to US and make dollars and complains about bad politicians, bad situations in Nepal, brag about lavish life in Foreign Nation and earning dollars, making a tik tok video??
