Dear,
You have recently done a case study on residency for me. I would like you to do the same thing for another case study regarding permanent establishment. I have added the previous case study you did on residency with the exact correction that was expected.and when you scroll down in the document you will find the exercise and methodology for the case study you would have to do now. This will maybe help you understand better what exactly was expected.
Just like before, I have added my course notes that will need to be used and followed when answering the case study (all information should come from there). As you might have noticed. The methodology on its own is very lengthy, hence this should not be included in the word count as this is only a copy paste (but should be included in the text/ answer you will give me)
Please let me know if you have any further questions.
