Obviously you need to make sure you have your visa in your passport, this is mandatory for most western businessmen before you even board the plane at your departure point.

You will have to complete a landing card so make sure you have all the information to hand including the address of your sponsor and ideally the sponsor letter. You may have to show this to immigration before stamping.

Your bags will be scanned and possibly searched AFTER baggage reclaim. One thing to note is if you have any cds, dvds and external hard-drives in your baggage is that they maybe looked at. Double check the contents of these before you arrive for any dubious material.

One likely hiccup is that at the immigration desk, your visa may not ’show up on the system’ and you will get told to go to another immigration desk. There they will process your entry.

Transportation. There are unofficial and official taxis. You will likely get hassled as soon as you enter the arrivals area by unofficial taxi drivers.  It is my experience that there is no difference between the two…ie for a trip into Jeddah you will have to pay a fixed rate with the official metered taxi, and the unofficial taxi will also offer you fixed rate. They tend to be about the same : 60 or 70 riyals. The official taxis generally want to take people who are on Umrah (the hajj ‘lite’) so they wont care for your business if you are going to Jeddah.

Banking and ATMS. There are a few of these in the arrivals hall.
