is there any way to change job and income in icici like they give in hdfc bank account setting ????

Ask hdfc customer care

Just submit docs (mostly oral is enough) saying update of income proofs  by visiting branch and in hdfc they can easily do it from branch

for icici i dont know sadly

No matter what income you fill in form, it doesn't matter for getting cc approved unless submitting proof of that income in the form of salary slip/itr.

They have option to change profile details in app, do you have icici savings account or you are cc user only?
