Ordinarily child support will cease on the child's 18th birthday unless there are mitigating circumstances. If it's a case of back child support, it is owed to the custodial parent who carried the financial burden during the period of nonpayment.
That is first dependent on whether 18 is the age of majority for your state. In Mississippi, it is age 21, which is also when the support stops.
Second is whether child support extends beyond the age of 18 in your state. See link below.
Finally, the obligor parent would need to make an official request with the Child Support Enforcement Office to modify the order.
No, child support is only owed to the custodial parent/guardian. If the grandmother has become the custodial guardian, child support will be owed to her, instead of the mother.
Generally, no.
yes..
no
Child Support Enforcement will an interstate action under the UIFSA.
Yes, but you'd have to file an amendment (order modification) to the existing order with a request for support for yourself.

Yes you can.
Depending on the state, yes. see link below
Yes.Yes.Yes.Yes.
Well it depends on the law of the country and demands of the parent (the one that's living with the child).
When a parent moves to Germany, and has children in the United States, he does have to pay child support. If he is evading child support; Germany will demand he continues to pay support.
