This is exactly what is going to happen. Next year when you go to renew your visa, they will show you your world wide income, or at least income from your home country, thanks to the new global reporting.
The message will be: You owe us this much, and you have to pay now. If not we will not renew your visa, and until you pay we will put you in the immigration detention center.
Trust me. This will be close to the truth.
