If you say so. That is direct information given from the boss at my local immigration office. You know, the guy and his staff that I buy a big cake for every time I do a 90 day check. ????
As you know, they have, as always, the possibility to abuse that legal system. It´s easy for them to make check as they wish outside, as most of us do not know as well as they will always have back-up saying that an anonymous report was made.
The reason I asked them, if they had a system they can see if a person is overstaying, was that a fellow countryman died in my city, and we had to help the family and his children with embassy contact as well as immigration work as his wife had left him and he took care of his two kids alone.
A knew he was on a super long overstay, and after he had died I asked the immigration boss if he could look how long. The only thing we found was an old 5 years ago expired passport, and they could not even see with that info.
