there is no confusion, my argument is that this is only true for the US. according to my experience no other country does it that way because in most countries, visa and status are one and the same thing. no visa, no status. or, if there is a difference, then extending your status also extends your visa, or vice versa. and you do it in the country. not outside.

i also reject the claim that there is no one inside any country that could verify the status of a foreigner, only consulates outside the country could do that. that is straight out nonsense.
