Hi Sonu,
We are an immigration consultancy based in the UK and help our clients make UK visa applications of all kinds. I have recently made a similar application on a same day basis for our client.
If your stay outside UK has not exceeded 180 days, you are within the rules. Also, you must not have lived outside the UK for more than 90 days within the last year immediately preceding the day of your application.
If you make an application using the premium service for your ILR, you are most likely to have a positive outcome on the same day. If you do not qualify, the case worker will most likely grant you an extension instead as long as you meet the criteria for an extension.
If you wish to discuss making an application through us, call us on 01908303753 and I will be more than happy to help you out.
Regards,
Harry Dhinoja
