I liked the Egypt system
Do it online, fill in war and peace or build the equivalent of a pyramid to explain your purposes for visiting. then take a paper print-out of the approval to the arrivals immigration officer
OR
join the queue, spend US$25 on a lovely visa and head for the immigration queues. Get a stamp and enter the easy way
I did a Dom on international flight recently. The Australian system of get a paper ticket etc etc is mind numbingly government bureaucracy
The saving grace of the e-gates is now Australians are a designated user of them at Heathrow. Took forever for the UK to fast-track Aussies when we both share a head of State. Shows the irrelevance of our bureaucratic nightmare in “dragging the chain” and “tug a lug lug the forelock”
