Hi, I am wondering does immigration change your age before you can come into this country? I have a be seeing a guy who is from Mexico and he says that the age on his passport is different than on his birth certificate because they made his age younger than he really is. I think he might be lying in order to date me, because if he is the age his passport says, I will be about 10 yrs older than him. His passport says 12-17-90, but he says that his real birthday is 7-20-1988. So, I am wondering is this true?
