As mentioned above, it will probably remain tied up within the judicial process for years to come, up until the children are of legal age to petition for their parents to remain in the US or Canada legally with them. Indeed, we shall see.
Immigration reform is next. Petitioning for relatives, parents, siblings, etc, should be greatly reduced in priority and legal immigration for those with skills that allow them to be productive should have priority. We shall see.
You may not be aware that the mere birth of a child in North America does not guarantee the child nor their parents the right to live in the United States or Canada, at least not until the child reaches the age of majority. Put another way, the family can be and often is removed from the U.S. or Canada, even if they have a native born child, because they do not have lawful status in the country. Some time in the future, once the child becomes an adult, they will be able to return to the U.S. or Canada, but that is down the road.
It does not prevent deportation now.
Once a citizen child reaches 21 in the case of the United States and 18 in the case of Canada, that child can return to North America and eventually sponsor their parents to legally immigrate to the country of citizenship. As for education in the meantime, unless the child can show legal guardianship or custody by a U.S. or Canadian citizen that would give them permission to reside in North America, they will not be able to study here, either.
