Munna and Jnathan,
Yes, Munna is Correct. SGVO asked over mail with an attachment if there is any changes in my employment and any additional experience which I want them to assessed then for relevant experience they are asking for Job responsibilities, Contract letter, pay slip and copies of income tax returns. So I merely sent the Income TAX certificate (well...my and my father's last name was a typo by Govt Certificate) along with my job roles and responsibilities, job contract and salary slip.
Planning to re-send the correct one once it get it from TAX advisor again with a covering letter.
