Personal experience,in my family,says this is required because it is so easy to get fraudlent docs in third world countries.
Still, a decent idea, though suspect that there are not so many cases of forged familial links (and what about marriage?) in the United States. People can easily cross the porous borders with Mexico and Canada (much longer and less patrolled than the Mexican border, if potential illegal aliens can get to Canada).
Finally someone with sense.
This would certainly speed up criminal investigations where no match can be found for DNA left at many crime scenes.
This is an excellent idea.
Medical testing was good enough for our grandparents and great grandparents, it should be a priority with those sneaking in and caught. No one mentions the diseases that are coming in from other countries and the multitudes filling our emergency rooms that we’re paying for. Next, we can discuss how many terrorists have also walked across our borders and are here awaiting orders.
