A successful business doesn’t mean personal accounts have lots of funds most people keep a lot of the money from the business in the business. Personal accounts are what count not the business accounts.I mentioned that he has a successful business. It's almost as if people have no idea how this works. The immigration agent can decide how much is "enough funds." I know this because I worked for IRCC on Slater from 2016-2017. There is no science to any of these decisions. The agent has discretion and no one checks the cases unless there is a complaint.
