Question about employment status and CCs

Hi I am currently working in a big audit firm. I plan to leave this company in a couple of months. I will be transitioning to working in my (small) family business. I am aware that it is not going to be found in any of the company name drop-down menus in any credit card applications as well.

My question is that once I switch, how will it affect my ability to get new credit cards and/or upgrade my current credit cards and credit limit.

Current credit situation: - ~775 CIBIL score - HDFC Indian Oil - American Express Platinum Travel - SBI Cashback - ICICI Amazon Pay - Auto Loan - OneCard (closed this month as it was a secured card and I had to break the FD)

If I don't generate a salary slip or anything of that sort, can I still get a new card/card upgrade from my CIBIL score or Experian score, or existing credit cards?

Will my bank statement be enough to show that I get a regular "salary" and display my ability to repay the bill?

Thank you
