I have to say that American INS officials are the rudest and most hostile I've encountered anywhere. People talk about the hassle of arriving in airports like Lagos, but it's considerably more friendly and hassle-free than the USA. My last experience of Houston was such that I've decided never to return to the USA for either work, courses or holidays. My company is now looking at buying European made helicopters to replace its Sikorskys as there are just too many problems getting visas to go to USA these days. The INS is buiding huge barriers to travel and trade with the USA that must be adversely affecting the American economy from both a trade and tourism point of view.
