Although you cannot submit any additional documents until the visa office requests it + your application has not crossed the processing time mentioned on the IRCC website.... you can send a Case Specific Enquiry (CSE) requesting the visa office to consider the following additional documents:
1. Not just business registration documents..... but evidence that your business is actively trading (chamber of commerce certificate, audit statement, company bank statement, POs, 2 years ITRs, etc)
2. Property ownership documents + latest property tax receipt + self valuation/valuation by a CA
3. Financial investments: FDs, RDs, mutual funds, shares, LIC, etc
4. Family ties: Marriage certificate + birth certificates + any other dependent family members + an explanation that your family is not accompanying you
5. A day-by-day itinerary with expense estimates.... and prove that you have the finances for your visit
You can prepare a combined PDF for these documents.
In case your TRV has already been processed, these additional documents may not be considered. You'll have to wait for a decision based on the documents you have already submitted
