no country would imprison its own people in a 'high security prison' for forgetting a visa...i m sorry to notice u r changing the goal posts by comparing how US officers treat indian citizens. the question is how would US officers treat returning US citizens?
with courtesy and consideration....however, if they did have a criminal record or they were suspicious...your favorite prison comes into play..with of course a lawyer and a trial...
MERA BHARAT MAHAN...is not just a slogan...its a mentality...its an idea..and a way of living...it should be reflected in everything we do....the first point of contact is the immigration console...
just because WESTERN embassies are inconsiderate to indians....infact, all the more reason to be even more accomodative to returning indians.
