And thanks Bubba, those are issues to be considered, but he has checked out. He was born abroad to foreign parents. The parents immigrated here when he was 3 years old. The parents made the mistake of registering 2 different birthdays in the same month. So, for all his life he thought his birthday was 20 June.
He obtained his Citizenship Certificate from his parents a few months ago, and much to his surprise it says 6 June. So, now he does not know his actual DOB.
And yes, I don’t know much about citizenship law which is why I started this thread. I know that there are a few foreign born people and people married to foreign born spouses that patronize these boards, so I thought they could help out.
Thankyou all—he will likely just get the passport and call it a day.
