Hi. I am Currently have a Work Visa under the Essential Skills Scheme. I receive a new Job Offer from a different employer and region. As I need to apply for a new work visa my question is about the moment when the new Visa could be granted. Does the old work visa get expired inmediately or the INZ give a period of time to work in the old comany and respect the notice of period rule and then the old visa gets expired? I would be appreciatte if anyone can help me with some info about this situation

Thanks!
