Despite following "proper procedures", these effin' immigration officials at the airport continue their corrupt practices. I was almost a victim and frankly I wished I would have arranged for a business visa coming here as well so I could have had better career choices. I agree with Nomad, unless you are a criminal or have any hold departure against you, no one should curtail your constitutional right to travel as long as you satisfy the requirements of having a valid visa and a passport. Let it be the decision of the immigration of the country of destination to let you in or not.
