Let him visit them when it is convenient would seem reasonable.

Each situation is different and each country is different. I would find a Family and Immigration Lawyer and nip this in the bud. As you said, once the children are their on a visit, it is also my contention, as it is yours, the children will not be coming back without a larger fight. Right now you have the "gold" so you can make the rules with the help of a lawyer.
 
If there is a possibility you may want to look into providing the parents with a ECO Show from Amazon and one for your family. If the parents can see the children when they are talking it greatly enhances the experience for them and since in the past they seem to have control over "him" it might be a small investment for your personal family time. I wish you the best.

Doesn't matter if it's legal or not. International child custody violations are notoriously difficult to fight. I would NOT let the children travel back to meet him, personally. Can he not obtain a visa & visit them in the US? Or meet in Mexico, with you & your wife as well as the children? Like I said, I would not let the children travel to him.

No, we are in Kentucky, they are k2 and they have not visited yet as we are still adjusting status.
