Are there any time limits for receiving a CoS and applying for leave to remain?
Yes you must have been granted a CoS within 6 months of the job being first advertised. The only exception to this is Research Associate/ Research Fellow roles where you must have been granted a CoS within 12 months of the job being advertised. Once you obtain a CoS you must apply for leave to remain within 3 months else it will expire. In addition leave to remain can only be applied for within 3 months of the commencement of your employment, as stated in your CoS.
