Removing Ballpoint Pen From Old Paper

I wouldn't try alcohol or anything. The alcohol would just migrate and would probably give you a halo of the ink over large sections of your paper. If it is just asthetics, scan the document and clean it up on a computer. Or you can easily order a new one from the state you were born. I wouldn't try to change any of the original information though - that could only lead to trouble.

Call the nearest museum and ask to be referred to someone who knows how to work with valuable documents.

If it's an official document, it is probably illegal to alter it.
