Hey all--I thought I might share my story so that anyone else might avoid the problems I ran into.
In April of 2018, after about a year in VN, I went on a normal visa run, but I had stupidly misread my visa expiration date, It read 5/4/2018, and as an American, I read that as "May 4th 2018", but it was really "April 5th 2018". That was my mistake, I've been traveling for years--it's the first visa related mistake I've ever made.
I had overstayed something like 27 days, inadvertently. So I immediately I went to the immigration department, they took my passport, and I had to write down on a piece of paper why I overstayed, so I wrote the truth.
I also had to write what I was doing in Vietnam, and I wrote that I am a photographer and a professional dancer (salsa), both true.
A few weeks later, I paid about 4mil VND and got my visa back. I asked if I would have any trouble entering the country again, and they said "try for a new visa". I specifically asked if I was on any black list as a result, and they just kept saying 'apply again for a visa'.
I didn't suspect anything else, and everyone I talked to, including travel agencies AND the agency that works directly with the immigration department, said there's no chance I'd get on the blacklist for that infraction. After researching, I found out that the blacklist was for people with major infractions, so I was confident that I couldn't have gotten on the list that criminals end up on.
Well, then I applied for a new visa and got denied. I thought I made a typo, so I applied again. Denied. Then I thought maybe the agency was not doing it right, so I tried another agency. Denied. Then I went directly to the immigration department with a translator to figure out what was happening--they refused to provide any information.
So the immigration department suggested I go directly to their preferred agency--and I did that. After much persuasion, the agency was able to talk to someone inside the immigration department directly who was able to look at my file. The agency was told to 'stay away' and 'don't touch this case'. (!!?), and I was able to find out why I was put on the black list and for how long.
I was put on the black list because I was suspected of being an anti-government video-blogger or that I collecting information on Vietnam for the USA, and I was blacklisted until May 2020 (2 years). I was informed also that I could get removed for $3000.
I didn't really know what a video blogger was, and I'm not sure what information I would collect on Vietnam, so this came as quite the surprise me. Regardless, I can't argue what they "suspect" might be occurring, and I won't be extorted for the money--so maybe I'll return another year.
I was baffled as to how I got on this list, so it got me to thinking, and I think it was this: I said I was a photographer when they asked me what I was doing in VN. That was my first mistake. The second mistake was that I went to the immigration department directly--rather than through a lawyer or travel agency.
The travel agencies collect money and smooth things over with the officials--and I didn't follow the proper corrupt chain of command as I should have. My friend had overstayed for 4 months, paid a bunch of $ and had no issue returning--but he went through an agency who made up some story. The importance of an agency, is that they write down an 'appropriate' reason why there was an overstay (whatever immigration wants to hear), and money passes to the people stamping the papers. I think I was seen as a money making opportunity by the corrupt immigration officials and so was put on this list.
The lessons/things learned are the following
1. Of course, don't overstay ever (in any country).
2. Do NOT go directly to the immigration department ever. Work through a travel agency or lawyer.
3. Immigration will never tell you OR the travel agencies if you are or are not, nor WHY, nor for how long you are on any list. If you get denied for a visa, that's how you know. I knew someone who knew someone on the inside--that's how I was able to see details.
4. They can make up any reason they see fit to put you on the list; it doesn't have to be legitimate.
5. Your home country embassy will not help you, nor will get involved with Visa related issues.
6. $3000 will take you off any list and provide you with a 1 year visa.
7. Don't say that you're a photographer.
Anyway, I'm a legitimate, certified, experienced English teacher and I subsequently moved to China (oh my god the paperwork!) and got a wonderful job, where I'll reside until 2020 or so and then give visa application another shot.
I hope this helps some people with their own issues!
The only unanswered question I have is this: I got a new passport (completely new number) and I'm wondering what would happen if I now applied. Anyone have any idea?
Best of luck for those in similar circumstances who aren't criminals and get errantly placed on this list!
