Impostors may be a problem. But with more biometrics that is getting harder. Alien Resident Cards and US passports present a challenge to POE inspectors. Every visa issuance is vetted against the lookout system. Visa waiver country travelers to the US are subjected to an ESTA clearance before they fly.
