Unless the court order ordering him to pay child support specifically says otherwise, then yes. He could go to court to seek either to have visitation enforced or child support eliminated or reduced.
Depends on how long the visit is. But if the father is the non-custodial parent in this case, then he will have to pay child support on this child. Different states vary in their laws. But typically a "visit" will not affect child support.
If the father of your kids moves in does he still have to pay child support?
Yes, that is still your child and you have a responsiblity to meet the needs of that child.
Yes, he does. He is still a father, he has a child, and that child needs support.
If the court has awarded child support, then the good intentions of the father are irrelevant. Legally, child support must be paid.
I wouldn't think so let child support no he is living with you

Yes, he is still the father.
Yes, you will still have to pay child support because you are the mother or father of the child, and that makes you still pay child support.
