Seven thousand daily

So, we are getting 7000 migrants daily through the southern border. 7,000 × 365 = 2,555,000 annually (over two and a half million, for those who don't understand numbers). But, we are only accepting 100 thousand Ukrainians. I wonder why? Busing 200 migrants to D.C. might not put a dent on the problem. Especially, if they go straight to Union Station and hop on a train to Miami as soon as they're dropped-off. Are people aware that we don't really know who's coming through. For all we know, we already have an invading army in here. I believe that the invading country doesn't have to declare it has invaded, according to the Geneva Convention rules of war.
