Are you American and your husband Jordanian? If you are American your son will have US Citizenship. But, if you are not legally married in Jordan, your son will not have Jordanian citizenship (assuming your husband has it) if he does not have you listed in his family book. If your are not an American citizen, and your husband is, and ypur not legally married I am not sure how that would work. I'm sure he would get citizenship , but probably sonething extra paperwork, or the paper like you said. This is my understanding of the law, someone correct me if I am wrong.
