File existence loop?

Question

bash

Hello.
The following problem arose, we need a loop that will check for the presence of a file, if it exists, it will copy it to another directory, if it does not exist, it pauses, then re-checks its presence and so on until the file is created . As far as I understand it should be something like:

if [ -f имя.файла ]; 
then
  cp
else
 ???????
    fi

It's not clear what should be instead of ????
Thank you.

while [ ! -f имя.файла ]; do
  sleep время
done
cp
