You need to apply within 28 days before the expiration of your Visa. The Home Office knows the day you call for booking either by telephone or online. Due to the fact that applications are too many, you might be booked to a space after your visa has expired. It happens most times but don't worry, the HO understand the situation as it is their fault, not yours. It is never a problem at all.

Thanks a lot!

Hi all,
Since we know that ILR application by post is only required to be sent 28 days prior to the vsa expiry. But if I want to go through PEO same day service how many days in advance can we apply prior to the spousal visa expiry? Please advise based on your knowledge and experiences. I would appreciate.

Thank You
