You will be banned for two years if your current sponsor cancelled your work visa. You cannot get another work visa from another employer without NOC from your first sponsor. You must complete one year of service before you can transfer. And your sponsor must agree to give you NOC. NOC is the sole discretion of the employer. You cannot demand. You have to exit and go back to your country and wait for two years to be able to work again here if you get a new sponsor or employer.
