The southern border is about half the USA illegal problems.
About 1/2 come in from the Far East/Asia/Pacific regions thru
the west coast. They come in legal by visas but don’t leave
when the visa expires. Number wise these are now estimated
to be as large as the illegals that cross the Southern border.
if that’s the case- then the numbers have doubled- meaning the costs are now well over a trillion per year- The figures i posted above are mainly for south of border illegals I believe-
