By complications, I mean standing there having the officer either ask many questions and/or have periods of long silence (4-7 minutes) where the officer sits and looks around while holding my passport/visa. Getting through customs is quite similar as well, especially when I have checked baggage with electronics. I've had instances where they wanted me to pay some sort of tax on my company's laptop that I use for work. I've been to Vietnam 3 times and all 3 times have been similar experiences. After the 2nd time, it was not so dreadful and unpleasant so now I kind of consider this experience as one of the key "experience" to have when visiting Vietnam. I carry a U.S. passport with a proper Vietnam visa, so I am interested to see if anyone else share similar experiences. I've heard the officers look for money within the pages of the passport, which I have never done, so that may be the reason why they are giving me a tough time in hopes I would pay my way out of the inconvenience. Any truth to that? I'm about to leave for the 4th visit next month.
