Can I transform my American green card into Canadian green card?

Not directly. There are ways to search certain databases. If you had access to the SSA database, then the SSN would tell you if the person is a U.S. citizen or a foreigner.

Some DMVs have the information because driver licenses in certain states are differently designed and sometimes have different expiration dates than those of citizens. The U.S. Department of State's database would reveal if a U.S. passport has been issued to that person, ever. The DHS database would show if an Alien number for the person exist.

However, all of this is privileged information, requiring security clearance. Why don't you just ask the person? P.S. If you have the SSN, you can determine when it was issued.

So if the person is 20 years old, and the SSN is from 1992, they most likely are a natural-born citizen. If it's only 10 years old, then the person is an immigrant. The newer the number is, the less likely it is that the person has naturalized.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
