A Birth Certificate
yes by changing it on birth certificate
Its a 12 in the UK, but the British Board were thinking about classifying it a 15.
It's most likeley to be be a 12a or PG13 depending on whether you're in US or UK. It contains moderate/mild violence.
no not that i know of and yes you do need your birth certificate because how would you know if they were born in the USA or not. Because you can ask the person and they could lie to you and you...
