Thank you for your enquiry. The employer will inform the Home Office about the termination of your job which means that you and your dependent will need to leave the UK so that you do not overstay. In relation to your wife, we would need to review her contract of Employment in relation to maternity pay but she needs to inform them as she will not have leave in the UK once her visa is curtailed. Please contact us for more details on 0203 959 9123.
