If you get an ARC and for some reason you leave your job(i.e.fired, quit) is your orignal visa before the ARC still valid? What if the original visa in extendable and mulit-entry?
As your visa is cancelled as soon as you are issued with an ARC, you must apply for a new visa if your ARC is cancelled (check the visa in your passport. If has a “used” stamp on it then it’s no longer valid).
