I am the son of an adopted father. My father has never known many
things about his life since he was abandoned at the age of 7. My
father has tried many times to find out about himself, but the
governement will not give him any information about his parents or his
ethnic background(They say they can't release information because they
must protect his parents).
I am 16 years old and am beginning to search for colledges and am
looking for scholorships, and I have noticed that there is many many
scholarships based on your ethnicity. There are also many other
opportunities that can be presented to you if you come from a certain
ethnicity. My question is since there is no way that I can find out my
true ethnicity, is it possible for me to just say I am a certain
ethnicity like part american indian or african american? For all I
know I could actually be american indian, since Im kinda dark skinned,
then I could become rich off casinos and such. I feel it unfair for
the government to withold this crucial information from me and my
family.

College does not have a "d" in it.  (I would let the first instance
go, but you spelled it that way again.)

Have your father hire a private detective.
