In case you are not covered by enactments cited in above mentioned thread and service conditions are governed by appointment letter then you may close the issue by obtaining payouts after adjustment of notice pay and documents, by your last day in office.
Once you have left for abroad it shall be difficult for you to followup.
The employer can waive off the notice period/pay. If you wish you may apply your rapport, goodwill, persuasion, persistence, reasoning, negotiation skills and resolve the matter in your favor. If employer i.e appointing authority, MD etc agrees obtain the concurrence in writing.
Try and separate at a good note and defend your interest too.
