@sharath_natraj, my application included high salary as an evidence.
My page 1 was about my job title, my total compensation and other financial benefits which I converted to GBP. I also include a screenshot letter from my HR which stated my role and my compensation.
In page 2, I explained why my salary is considered high by using data from payscale. I included charts/graphs from payscale and provided links which shows the base, average and high range salary for a solution architect in my country . I went further to give a brief context into payscale, what they do and highlighted some of their awards.
In page 3, I tabulated my earnings, commission, retention bonus and stocks from my previous employment. I went further to explain why I was given the bonuses and stocks considering that they are not part of the standard employment T&Cs.
