So one of the wife's friends/acquaintances recently visited from Vietnam. She showed me an interesting thing. In her passport (and on her white immigration card), ICA stamped her with a normal thirty-day visitors pass. However, they also wrote down the exact date, time, and flight number of her return flight on both the card and in her passport. She probably sets off a few red-flags, as she's 20-something, single, and has visited a couple times in the past year or two.
I was a bit curious why they do this. Her friend thinks it means she must leave by that point, and can't stay any longer. I'd assume she gets the full thirty days, otherwise they wouldn't even let her in with a 30-day stamp. As anyone else who knows anyone from Vietnam will tell you, no one there keeps a schedule or can make a decision about dates/times. Vietnamese Airlines probably makes most of their revenue in ticket rescheduling fees.
So does the notation mean anything?
