There are a few
reasons.
1) We’ve seen the impact that their peoples’ belief
has on their ability to see ghosts or magical creatures.
Hima sourced that 23%
of Americans believe in ghosts; it’s not enough for America to be able to see
them, even though they exist in canon.

Because approximately 70% of Britons believe in
ghosts/supernatural beings, England’s able to see them.

2) Since Americans are really big on Halloween, and
tend to believe in the supernatural on this specific day, America’s likewise only
able to see magical creatures and ghosts on Halloween.

3) England claims that America isn’t “pure” enough
to see his pet unicorn.

However, as I’ll get into in a later post, it seems like as
time shifts, and his people’s belief in the supernatural subsequently grows,
America’s gradually gaining the ability to see them more consistently.
Ex: He goes on a citadel tour with England and mistakes ghosts as staff members.

When he takes a picture of them, they fail to show up. Confused, America still seems unable to make the connection. Perhaps he hasn’t yet realized that he’s acquiring the ability to see them.
