We left the airport ! We had some anxiety wondering if we would be able to leave because of so many reports of people who were not able to leave but I just wanted to put a little hope out there for others that we were able to leave really easily. Our layover was from 6am to 830pm. We were given a yellow arrival card on the plane and filled it out, we exited the plane and went to foreign arrivals and scanned our finger prints and took a photo. (Do NOT go to visa on arrival or to transit passengers if you are hoping to leave the airport) . We continued in towards foreign arrivals but all the way to the right is a line for 144 hours and twov. There is a blue card there you need to fill out before getting in line. We went with these papers and got our stamp and we were out of there ! Took maybe 10 minutes. We had to go to terminal 2 to use an ATM that would use foreign cards and give us cash needed to buy a train ticket. Sorry I can't give more specific details but there are a lot of great posts with step by step details. We tried telling our airline at check in that we wanted to go out and she said that wasn't necessary. Hope it goes that smooth for everyone else !
