The custody issue would probably depend on the country in which it is tried and where the child resides. It is likely that the child will remain in the country he or she is living in.
Whoever it is better for the kids to live with.
No
The mother has presume sole custody and control, regardless of the circumstances in all states.
Better for her to straighten out her citizenship status first. Without that, she is opening a can of worms regarding her stay in the US.
Can, but as she moved away initially, a judge may not consider it.
He can but I doubt he will get it since immigration status has no bearing on custody and parental rights..
If the grandmother has custody
Yes
Yes. In custody court it can be established that the mother is unable to properly and safely care for the children due to her unstable psychiatric history. Supervised visits with the mother may also be court ordered.
The mother can legally retain sole custody of the child until the father establishes paternity and files for custodial rights. This is an issue that is covered by "common law" and would apply regardless of the resident status of the mother. If the father chooses to petition for custody, the issue would be decided by the court based upon what would be best for the child.
Yes
well they would have to be adopted or the friend would have to be a foster home
yes
