One of the problems on overstayers is that we have no control of people who exit the country. If you are an overstayer. a visa overstayer in England. a cop comes to see you at your residence about 2 or 3 days after your visa has expired because they have a computer of who is leaving the country. and if you have not left the country. a patrolman shows up. very politely. and asks you to go down and see the Home Secretary. In this country. we have no control who leaves the country. and therefore. we have no idea of whether people who come in for 6 months or a year on a student visa. a business visa. a visitors visa whether they are overstaying or not. and that is a fatal flaw in the information and the data that our Government has and that our Congress has. We must remedy that.
