Thank you TheRealCanadian for your reply.
What do you mean when you say:"Automatic cancellation of the visa"? When someone overstaying, it means that their visa is already expired (hence the term overstay) thus, there isn't any visa to be canceled, right?
Also, if there isn't any ban for those overstaying for less than 180 days, does it mean they can apply for another visa in the future? Is there a record with USCIS about the overstaying period which then prevent an overstaying alien to get approval of their visa application?
