sudo -u user bash works but $HOME is not changing accordingly

I'm writing a script to setup new debian install's.
The problem is in this code:

if [ ! -z "$USER1" ]
then
 sudo -u "$USER1" bash <<-EOF
 cp "$BASHRC $HOME"/.bashrc
 wget https://raw.github.com/trapd00r/LS_COLORS/master/LS_COLORS -O "$HOME"/.dircolors
 echo 'eval $(dircolors -b $HOME/.dircolors)' >> "$HOME"/.bashrc
 . "$HOME"/.bashrc
 echo "Here is LS_COLORS in action: "
 ls -l "$HOME"/ 
EOF

PROBLEM:

When I sudo to another user the $HOME variable is not showing/changing this new users home directory.

QUESTIONS:

Can you explain to me the problem?

How would I do this in the best and efficient way?

Edit:

Why do I keep getting "cp: cannot stat '': No such file or directory" or "cp: missing opereand" in my cp command? I think it has something to do with $HOME again..........

The here-doc content is evaluated BEFORE the sudo is called. This means that every instance of $HOME is in the context of the caller, not the sudo. You can see this in action here:

A=apple
bash <<-EOF
A=banana
echo "$A"
EOF

The output is

apple

If you quote your EOF marker its contents will be quoted correspondingly:

A=apple
bash <<-'EOF'
A=banana
echo "$A"
EOF

Output

banana
