Unfortunately the custodial parent would not be successful in attempting to enforce a support order against a non custodial parent who resides outside the U.S. Neither state nor federal agencies have legal jurisdiction in such civil matters.
What is possible is, any assets such as bank accounts and property belonging to the non custodial parent that is within U.S. jurisdiction can be appropriated and used for the absentee parent's child support obligations.
In some situations the custodial parent can file a lawsuit for support in the country where the non custodial parent resides. This action, however, can be very expensive and lengthy in nature with no guarantee of support enforcement even if an award is granted.
It can be done if the father is living in a country that has an agreement with the US - contact your State's child support agency.

No, child support can only be taken from the birth parents.
Some countries have reciprocal agreements with the US to collect child support. I suggest that you contact your State's child support agency. When you get an interview with them, bring all the papers relating to your child support: birth certificates, acknowledgments of paternity, court orders, payment records, etc. Be polite but persistent. Good luck!
Yes, if the father has more time with the child than the mother, she will owe him child support.
The father can file for this change.
Contact the child support agency in your area in charge of disbursement/enforcement. They can probably obtain that information.
Marriage of the mother, father or child have no relationship to the collection of a debt.
if the mother terminates her rights can he collect child support from the mother if child lives with him?
If he was deported back to a country that has an agreement with the US there is no problem, just contact your State's child support agency. If it's a country the US do not have an agreement with you have to apply in his country.
no the mother should have the legal obligation to take care of the child
