I have an illegimate child which I don't have custody of, nor any access and therefore I can't have access to his photo to include in my DS-5501 form. And now I am selected for DV2023. I believe i have a valid reason not have been able to include the child in my entry form. Will this work against me? Any advise how I can address this in my DS-260 form?Thanks for any advise out there.
USCIS may well consider the omitted information to be relevant and material. Even though you have neither custody or visitation, those could be changed in the future by a court having jurisdiction. Even more seriously: depending upon the parents' circumstances and the law to be applied by the court, you could in the future be ordered to pay support for the child.
Because the existence of the child is likely easily discoverable by USCIS, you should disclose the child when completing your DS-260. Include an explanation about why you did not disclose the child's existence when you completed the DS-5501. Your explanation should be concise, factually correct, and non-emotional.
