He was not older than 26 when he received his green card. He fit the guidelines of needing that selective service registration number. He is now over ten years past (37 years old) and we are now wanting to complete the citizenship paperwork. He supposedley was automatically entered into selective service when he signed on his I-485 paperwork. However, when I enter in his number, info, name etc. the system shows me that he does not exist for a selective service number.
