The immigration department need this details to confirm whether I have applied under correct NOC code.
They have mentioned in their mail, that if I fail to provide this letter then it will result in rejection of my application.
What is the legal remedy to obtain such letter ?
Please do not look for legal remedy. Legal process will constrain the relationship.
Ask your Nephew to talk to his/her HR politely and explain the requirement. In general in most of the Companies HR follow standard format for employee related certify letters like bonafide certificate, salary proof certificate, experience, relieving certificate etc. Actually there is no rule in any company that HR should not provide such letters like employment reference letter. But HR will mostly be reluctant to issue certificate for unknown fear. When some one repeatedly follow up they will issue after confirming with their superior.
