Wait, Annual income: 12 Lakhs? After 15+ years in the investment management business?
Ok. Something is amiss here. There are two possibilities. First, if you are an employee, then the annual income is too low for your experience and hence a red flag. Second: You are a partner and hence the salary is just a nominal salary. In that case, you have to document your Annual Gross Income including Bonus, Dividends etc. In the second case you have a possible answer to "what changed": You misunderstood that the VO was referring to Annual Gross Income; you just quoted your salary. If that is the case you have a genuine case and should consult a US immigration attorney who has a presence in India.
