How long time wize does it take to get visa?

Its not a visa but a visa waiver called Transit with out Visa or Visa Free Transit. You can only get this if you are in transit to a third country. How long it takes depends on how many other people are also applying. There are two different lines that you will have to wait in. First one is to get the 144 approval which can be as little as 5 min or an hour if the line is really long. Then once you have that you can go to the immigration line and then collect bags, I've had it take as long as an hour to do it all.
