Dear The Recruiter,

The process which I am sharing it with you all is the one which I underwent. Whatever was asked to me for a prospective job process I had to undergo all these. Because when you are advised by the employer to go to Labour to submit the docs for their approval, one of the main document required is your degree certificate duly attested exactly the process I stated above, that I underwent.

So I am unable to say anything on your comment as to why you were not asked the same way, this has to be clarified with your employer. Overall, if you dont want any delay, just exactly do what they tell you to do at that moment without any assumptions based on the info you already received.

Good Luck.
