I had gone through the process to obtain a work visa at the UAE embassy in Washington, DC. I then flew to Zurich for several days of meetings regarding the assignment. Before leaving Zurich, I confirmed everything was in order at the UAE consulate there. My mistake? I took 5 days to visit Cairo before traveling to Dubai. Once there, I heard these words which would be repeated over and over while there - "since yesterday, the rule has changed". They put me in detention for about 8 hours. About an hour before being released, they told me I would be placed on a flight to Bombay. Then suddenly, I was released with no explanation. I journeyed to Al Ain from there. One of the longest days in my life. I later came to understand backshish (sp?).
And you know what? It was just as challenging to leave 6 months later.

I fortunate in Yemen in the early 1990's, that they had not yet learned just how large a bribe could be. A $2 bag of hard candy left on top of the clothes in the suitcase was all it took.
Typical entry at international airport:
The one security guy that speaks english takes me out of the security line, while others carry my luggage I'm no longer allowed to touch. The put them on a table and open each one and leave. Security guy points to the bag of candy. "What is this for!" I reply: "It is for you."
He picks up the candy, tells me to close all my luggage up and and I'm free to go.
A year later after hundreds had come in and out from Europe and the US for our project, it wasn't quite so easy or cheap. Baseball caps worked for several months, eventually the wanted US cash.
