Use of CD in Bash For Loop - only getting relative path

I have a small script that I use to organizes files in directories, and now I am attempting to run it on a folder or directories. MasterDir/dir1, MasterDir/dir2, etc.

Running the following code on MasterDir results in an error as the $dir is only a relative path, but I can't figure out how to get the full path of $dir in this case

for dir in */; do
    echo $dir
    cd $dir
    cwd="$PWD"
    mkdir -p "VSI"
    mv -v *.vsi "$cwd/VSI"
    mv -v _*_ "$cwd/VSI"
done

I'd suggest using parentheses to run the loop body in a subshell:

for dir in */; do
    (
        echo "$dir"
        cd "$dir"
        cwd=$PWD
        mkdir -p "VSI"
        mv -v *.vsi "$cwd/VSI"
        mv -v _*_ "$cwd/VSI"
    )
done

Since that's running in a subshell, the cd command won't affect the parent shell executing the script.
