If the child was born in America, the mother can request the residence in the United States. This is the legal principle of jus soli (law of ground) which grants birthright citizenship to anyone born within the United States; a principle that was established in the Immigration and Nationality Act of 1965.
However, if the child does not have American citizenship, it is still possible to fight for child support and alimony (spouse support) due to this very fact: the mother can't work since she is unable to do so and she requires support both for her as well as for the child.
Only the court can approve the child being removed from the country, which is unlikely, as Mexico does not honor fathers parental rights.
If you were born in Mexico, you are Mexican. If your mother OR your father was born in Mexico, you are of Mexican descent. If your parents' ancestors were born in Mexico, you are of Mexican ancestry.
Her mother
that depends on if the mother has custody over her daughter or not. It also depends on how old the daughter is. If she is under the legal age limit, then the mother is still responsible and makes all decisions for her. If the mother does not have full custody over the daughter, then the mother and the father of that child must come to an agreement on the living whereabouts of the daughter. If the mother has legal custody over the daughter and the daughter is not of legal age yet, then yes, the mother can bring the daughter over too.
For 1) are you in custody of your daughter? If you are in full custody you could take her to court for kidnapping is your EX mother in law in custody of your daughter? Do you have joint custody? If your ex mother in law has no custody over your daughter you could take her to court, she is not authorized to take care of your child.
If not married, the mother always has sole custody, even without an order. see links below
i don't think so.
The mother assumes automatic custody, unless she is unfit.
