Re: marryin 4 greencard
after a certain number of years the greencard that someone gets through marriage becomes non conditional. i.e. its no longer dependant on the two people being married.
Now you have an option to try and convince authoities that he was in the marriage ust for greencard and as soon as teh condition was lifted he bailed. I dont know what the success of that argument would be though.
The guy should not be left off the hook for child support though, the sooner he is hit with it, the bigger issues he is going to face. Back payments and all that.
You have to get your timing right though, because they calculate child support on many factors including the person's current income. so if he is not making a lot of money in Pakistan, while he would still be liable for paying a minimum (which can be quite a bit if he is earning in pakistani rupees). Versus if he comes to US and then starts working then from a child support point of view, you may get a bigger check.
I can understand the motivation for vengeance and to get him thrown out of the country and all, balance that with the child support he would have to pay so the child can have a better life.
Talk to a lawyer, figure out the different options and see what gives you the biggest benefit.
