OB is not acting like an innocent man. Spending nearly a million to hide your birth certificate is either extremely wasteful or there's something wrong.
People file lawsuits against you and you have to respond or lose by default, even if the lawsuit is totally frivolous. Responding means lawyers and lawyers cost a lot. I don’t think his hiring lawyers to defend a suit means anything.
You have a valid point there. Most Americans have the good fortune to be out of any problem, when born there. Only those who have had the misfortune to come across a zealous civil servant would possibly understand. I would not even refer to the case at hand yet, but I would imagine the practice was well known. Just put the child as being born in America, hardly considered as a sin, by informants. People have gone through hell, thinking they were legit and someone finds out they came into the country at six months of age or so.

However I certainly don't know that.
