Yes sir, to your utter dismay, I do indeed, find it hilarious because of the proximity of the two countries and the relationship between the two countries.
But I do not find it hilarious when a person from Bangladesh may be traveling on a one way ticket to USA and denied check in or a person from Bolivia may be traveling on a one way ticket to Spain and denied entry.
My point was, that every law ever made is subject to interpretation , depending on the person implementing it. Like I said, any person can overstay despite any type of visa or air ticket in their possession.
If a Argentine flew from BA to Montevideo on a one way ticket - I would be shocked to see him getting deported by Uruguayan immigration and aerolineas argentine being reprimanded. ( In fact last month I had flown on a one way ticket to Montevideo on Aerolineas and no one at aerolineas asked me a return ticket. And immigration at Montevideo, did not even ask me what i was doing there though I had filled up "business" in the entry form.
Just my 2 cents.
Why on earth would I be dismayed because you find "hilarious" a global immigration regulation that has been in effect for more than fifty years? I'm just stating facts, pal. It has nothing specifically to do with Argentina or Uruguay or Bangladesh or Bolivia. Nor does it have anything to do with the proximity of any two countries and the relationship between those countries. Again, this is a global immigration regulation, period. Just accept it, kiddo, for it's here to stay, whether you like it or not.
Just my 50 cents.
