Few countries have visa exempt stamp process so anything above that needs to be vetted properly and 20 million came last year to a country of 46 million that is a lot of people to process man6 more than the USA do and try getting a visa through the USA .. you have to mail it in prior to an interview process, obviously you don’t know what a foreigner goes through in the USA to stay
your stay is being real lazy ... tell the immigration officer and they can send a police person around to read him the riot act and fine him in to doing it next time properly ...
