There are a couple issues here. For your husband: *Consulate Processing* Consulate Processing must be completed. This allows the petition to first be sent to the National Visa Center, and then the appropriate documents and package to go to the U.S. Consulate or Embassy. If done correctly, you will be able to enter as a Lawful Permanent Resident and will be in the U.S. in less than one year. Of course the time might be a bit less or more depending on the backlog of the U.S. Consulate or Embassy and whether or not a Waiver of Inadmissibility is needed. For your children: *Derivative Citizenship* In some cases, people are U.S. Citizens and do not know it. In this case, it is possible for us to file what is known as a Derivative Citizenship Petition. It is a petition that if approved, will give proof of U.S. Citizenship. There is a significant amount of evidence that would be required for this type of petition, but if done properly, there is a reasonable chance of success.
