I got married last year in August. My wife has already got a discretionary leave and her 3 year extension is due later this year. I have been on Tier 2 visa for over three years now.As you all must be aware Tier 2 visa has work restrictions and rules surrounding it keep on changing. I am very focused when it comes to my career and when I took this visa I was aware that changing employer would be very difficult. I received tremendous response to my job applications but visa transfer remained an issue to most employers. It came to the point that I stopped applying and started waiting for the 5 years to conclude so that I could apply for ILR.
I was not planning to stay in UK at one point but then I met my wife and I never felt like leaving it again

I want to progress with my career but my visa rules more or less mean I have to be with same employer. This is really frustrating at times. I understand that a spouse/dependant visa do not entail work restrictions. Neither do I want my wife to become my dependant as Tier 2 is an uncertain visa when it comes to ILR.
Can I apply for spouse visa on my wife's discretionary leave? If there is this route I will jump in the air with excitement! This will greatly enhance my chances of securing a new job!
Thank you!
