Singh-pun123: Once your RP is cancelled by your company, you must leave within 7 days from the date of cancellation. Otherwise, you will need to pay a penalty for each extra day after the expiry of 7 days.
As per the last information I have, you will be needing an NOC in your case as you have not completed 5 years. But please wait for comments from other QLers who may be knowing better.
As for getting clarifications on labour issues, I suggest you visit National Human Rights Committee office. They will guide you. They will also answer your query whether you need NOC from your employer in your case.
