The $USER variable is tricky and could display another user than
expected, that's why scripts should use $(id -u) when checking for
root and for your task you should consider using ~ or $HOME instead
of /home/$USER/.

$ echo ~ $USER $HOME $(id -u)
/home/rocketmouse rocketmouse /home/rocketmouse 1000
$ su
# echo ~ $USER $HOME $(id -u)
/root rocketmouse /root 0
# exit
$ sudo -i
# echo ~ $USER $HOME $(id -u)
/root root /root 0
# logout
$
