Moving to Vietnam in 2026: The Language That Beat Me
I have studied languages for almost two decades. I learned Hangul in twenty minutes. I conduct business meetings in Mandarin. I read manga in Japanese without subtitles. I went after Cantonese on purpose because nobody else seemed to bother. Eleven languages later, there is exactly one I have tried, respected, lived with for stretches in Saigon and Hanoi, and never reached conversational fluency in.
That language is Vietnamese, and this is the post about how it beat me.
I am writing this because a friend asked me last week whether to take a job in Ho Chi Minh City. Two of my answers came out at once. The financial answer is yes, obviously, the cost of living is friendly and the food is among the best on Earth. The language answer is more complicated, and complicated in a way that other "moving abroad" guides do not warn you about, because most of them are written by people who have not actually tried to learn Vietnamese as adults. I have. Below is what happened to me, in order.
Month 1: the tone trap I did not see coming
I landed in Tan Son Nhat with the same arrogance I have landed everywhere else. I had a notebook. I had a plan. I had a Mandarin-shaped brain that figured out four tones years ago, so six tones (or five, in the south) was a manageable upgrade. I was wrong in a specific way that took me weeks to diagnose.
In Mandarin, when you mispronounce a tone, listeners often catch the meaning from context. Say "mā" instead of "má" and a patient Beijinger will sometimes work it out. Vietnamese does not give you that grace. The word ma alone has six meanings depending on the diacritic: ghost, mother, but, tomb, horse, rice seedling. None of them rescue each other through context, because they show up in similar slots in similar sentences. Locals will hear ghost where you meant mother, and instead of correcting you, they will look briefly confused and switch to English. That last part is the thing nobody tells you. The switch is gentle and immediate and it kills your practice loop.
I spent four weeks in District 1 ordering cà phê sữa đá with what I believed was a passable accent, and I was repeatedly handed something that was not what I asked for. One day I bought a bowl of bún bò and got a bún chả instead, and I spent twenty minutes trying to figure out where my pronunciation had gone wrong. The answer was: not the consonants. The tones. Specifically the huyền (low falling) and the sắc (high rising), which I was producing as if they were the second and fourth tones in Mandarin. They are not. They live in a different part of your throat and your Mandarin reflexes will fight you on it for a long time.
I was not a beginner. I had passed an HSK exam. I had recorded a Korean short film monologue. None of that helped. Vietnamese tones are their own thing and they punished my transferred reflexes harder than starting from zero would have.
Month 2: bureaucracy in a language I could not read
The 90-day e-visa is the clean part of moving to Vietnam in 2026. Twenty-five dollars, three business days, multiple-entry, completely online. That is not where you struggle. You struggle when you actually try to do anything that requires a piece of paper.
The first time I went to register my temporary residence at the local công an (police) office in District 3, I had Alysse on the phone. Alysse Hoàng is my cofounder at Mynago, Vietnamese-American, native speaker, and the only reason that morning ended with a stamped form rather than three more visits. She walked me through what đăng ký tạm trú (temporary residence registration) actually meant in practice, what thẻ tạm trú (the Temporary Residence Card) was for and was not for, and which of the four windows I needed to wait at. Without her on speaker I would have done what most foreigners do, which is hire an agent for two hundred dollars to fill in three boxes I could have filled in myself if I could have read the form.
That is the Vietnamese expat tax. Either you pay it in money (agents) or you pay it in time (afternoons spent at the phòng quản lý xuất nhập cảnh with a translation app that cannot handle the regional vocabulary on the signage). I paid it in both, and I had a native-speaker cofounder one tap away. My friends without that lifeline pay it harder.
I started keeping a list of office words I kept hitting. Hộ chiếu (passport). Thị thực (visa). Giấy phép lao động (work permit). Sổ hộ khẩu (household registration book, which you do not have but which forms keep asking about). Công chứng (notarization, required on more documents than you would expect). My textbook had taught me to order coffee. It had not taught me any of this. Mynago later filled that gap deliberately, because of this exact month, but at the time I was on my own with a phone and a stubborn cofounder.
Month 3: the moment I realized my Spanish brain was working against me
I am Mexican. Spanish is my first language. I have spent my whole adult life using my Spanish brain to find shortcuts into every other language I have learned. With French and Italian and Portuguese, the shortcuts work. With English, I borrowed enough cognates to fake my way to fluency in two years. Even with Mandarin and Japanese, I learned to look for patterns my Spanish-shaped brain could rest on.
In Vietnamese, around month three, I noticed something uncomfortable. Roughly a third to half of Vietnamese vocabulary is Hán Việt, borrowed from Chinese over centuries. Quốc gia (country) is 国家. Hôn nhân (marriage) is 婚姻. If you know Mandarin, you can read these. The trap is that the Vietnamese pronunciation is so far from the Mandarin pronunciation that recognizing the word on a page does nothing for your ability to say it, and the tone overlay makes production a separate problem from comprehension. So my Mandarin gave me a reading boost that did not transfer to speech, and meanwhile my Spanish kept pushing me toward Romance-language sentence rhythms that do not exist in Vietnamese.
The clearest example was pronouns. Spanish has tú and usted. Vietnamese has a system of relational pronouns based on age: anh (older brother / man slightly older than you), chị (older sister), em (younger), cô (auntie / woman older than your mother), chú (uncle), bác (older uncle, or older than your parents). You have to guess someone's age to address them. The first question you get asked in many introductions in Vietnam is how old you are, and it is not rude, it is the only way they can pick the right pronoun for you. My Spanish brain wanted a neutral default. There isn't one. Get it wrong and you sound either presumptuous or weirdly formal.
That was the month I admitted I was not winning. I had been studying daily for around ninety days, I could order food, I could take a Grab without the driver giving up on me, and I still could not have a five-minute unscripted conversation with the auntie who ran the bún chả place on my corner. She was patient. I was not enough.
I went home. I told myself I would come back to it. I did not, for years.
What my Vietnamese expat friends do (that I did not)
When I started building Mynago and added Vietnamese as a target language, I went back to the friends who had succeeded where I failed and asked them what they did. Three patterns showed up in every interview.
First, they committed to one regional variety on day one. Northern (Hanoi) for one friend who works in policy, Southern (Saigon) for two who are in the startup scene in HCMC, Central (Huế) for nobody, because nobody does this voluntarily. The friends who tried to learn "Vietnamese" without picking a region got stuck for years sounding wrong in every region. The ones who picked got to functional A2 in months. Vietnamese has three major varieties that are technically mutually intelligible and practically not, and locals will accept you faster if you commit to the variety of the place you actually live in. I did not commit. I was mixing northern textbook material with southern street exposure for the entire three months. That was a self-inflicted wound.
Second, they front-loaded tones for the first six weeks and refused to learn vocabulary in parallel. They drilled six tones (or five in the south) until they could hear them reliably before they tried to hold a single conversation. I did the opposite. I tried to bank vocabulary so I would feel productive, and my tones never stabilized, and so my vocabulary never landed in a listener's ear correctly. Order matters here. Tones first. Words second.
Third, they had a patient native speaker on a regular schedule. Not a tutor. A friend who agreed to one weekly hour, who would correct only the things that mattered, and who would not switch to English when the conversation got hard. The expats I know who got to functional Vietnamese all had this. The ones who tried to do it with apps alone, including a previous version of me, did not.
That last one is the hardest variable to engineer. It is also the one that mattered most.
What I would do if I went back today
I am not going back tomorrow. But I have planned what I would do if I did, because building Mynago Vietnamese forced me to think about it carefully, and because I owe my younger self a working version of the plan he didn't have.
I would commit to northern (Hanoi) Vietnamese on day one even if I was moving to Saigon, on the grounds that northern is what national TV and bureaucracy use, and you can pivot to southern by exposure once your foundation is stable. (This is a defensible call but not the only one. If I were moving to HCMC permanently and not planning to leave, I would pick southern instead.) I would spend the first six weeks doing nothing but tones. Cold listening practice, minimal-pair drills, slow sentence shadowing. No vocabulary banks, no Anki, no phrase memorization. I would record myself daily and compare to native audio.
I would use Mynago, because that is what we built it for, but I would use it specifically as the structured engine for the parts that benefit from spaced repetition (vocabulary, pronoun drilling, scenario rehearsal), and not as a substitute for the human practice partner. Mynago lets you pick your regional variety up front, which matters more for Vietnamese than for any other language we support. The Vietnamese expat life is regional first and national second.
One pattern worth flagging while I am on the subject. Overseas Vietnamese (Việt kiều, second-generation kids who grew up with the language spoken at home) have a quietly enormous Han-Viet head start when they pivot to Mandarin or Japanese. Roughly 60 percent of formal Vietnamese vocabulary is Sino-Vietnamese, drawn from Middle Chinese. The quốc gia and hôn nhân layer they grew up half-hearing maps directly onto the original Chinese forms, and the Japanese on-yomi readings sit in the same family. I have watched Việt kiều friends learn Mandarin in adulthood far faster than non-Vietnamese learners around them, and it is the substrate doing the work. Vietnamese is a hub language for that group in a way it is not for outsiders.
I would also, this time, build the human practice partner first and the app second. I would find a tutor in Hanoi on iTalki for two sessions a week before I landed. I would tell them to refuse English. I would lean on my cofounder Alysse for the cultural and pronunciation calibration the tutor cannot give me. (You can find her work on language and identity on her LinkedIn, where I post most of what I write about building Mynago, including the Vietnamese course decisions.) I would budget eighteen months to functional Vietnamese, not three.
The last time I tried, I gave myself ninety days and a textbook. That was the actual mistake. Everything else was downstream.
Honest advice for the friend asking me whether to move to Saigon
So here is what I would tell you, the friend reading this, who is genuinely considering Saigon or Hanoi for 2026.
Move. The cost of living is friendly. The food is some of the best on Earth, and I am from a country with serious food. The 90-day e-visa is the cleanest entry path of any major Asian country. The expat scene in District 1 of HCMC and the Old Quarter and West Lake of Hanoi will hold you up for as long as you need it to. You can have a comfortable life in Vietnam in English alone, in those zones, transactionally. That part is true.
But understand what you are giving up if you stay in English. You are giving up your xe ôm driver who would otherwise tell you everything about his neighborhood. You are giving up the auntie at the phở stall who would otherwise pull you into the regular crowd after three weeks. You are giving up half of Tết and most of nhậu (the food-and-drink culture that is most of how Vietnamese friendships actually deepen). You are giving up the part of Vietnam that makes people stay forever.
The way you keep that part is by treating Vietnamese as a multi-year project, not a 90-day language hack. Pick your region. Front-load your tones. Find your patient native speaker. Use whatever app you want as your structured engine, including ours, but do not confuse the engine with the road.
And if you are wondering whether the language is worth the effort: I gave up on it for years and now I am trying again, in part because of Alysse, and in part because Vietnam never let go of me. Some places do that. The honest answer is that Vietnamese is the hardest language I have personally tried to learn, and it is also one of the most worth trying. Both of those things are true at once.
If you go, write me. If you fail at it, write me anyway. I have been there.
