How long can I keep my son from his farther until someone above tells me I have to let him see my son?

If you are not married to the father, you only have to let the child see him if there is a court order to do so. If there is a risk of the father fleeing to Mexico with the child, go to court, get a proper order, including one that has you have control of the passport and prohibits the father from taking the child out of the jurisdiction. Then write to homeland security, send a copy of the order and he will be put on a list so he can't take the child out of the country.

An experience lawyer would have to review the situation with you to determine the father's rights. It is generally safer for you to obtain a court order to prevent the father from removing the child from the State. Generally, you do not have to allow the visitation until the father obtains a Court order.

If there is no court order, you can keep him until his father gets him. Not a wise choice. You need to go to court to determine custody, now, and get an order limiting the father's visitation. You may be able to use the fear of his going to Mexico as a basis for supervised visitation, but there is no guarantee of that. You should really talk with a local attorney about it.

If there is no court order then you do not have to let him see the child. If there is a court order then you should change the visitation and get passport provisions. Otherwise you are in contempt of court and can face fines attorney fees and even jail time.
