My wife came to the UK with a fiance visa. Now we married and will extend her FLR(M) visa soon. But I got the best opportunity job that earns money a lot much more. My current salary is £19,600 per annual but the new job is £23,000 per annual. And it will start on 29 April, 2019. and last payment from the old employer is will pay on 28 April, 2019. The problem is my wife need to extend visa soon cause her visa expired on 18 of May, 2019.
What do I needed to proof to Home Office ?
And I know that FLR (M) is apply online only, how difficult it is?
