Overstay + visa run: the trap
The idea comes up constantly: "My visa expired, but I can just do a visa run to Lao Bao and get a fresh stamp, right?" No. A visa run does not fix an overstay. It is the one move that reliably makes everything worse.
Here is the mechanics of why. A visa run works because you exit Vietnam legally and re-enter on a new visa. The exit is the load-bearing part. If your visa is already expired, you have nothing legal to exit on. Vietnam's exit control at Lao Bao checks your records the same way the airport does. The system flags you, the border officers stop you, and instead of a quick Laos stamp and a fresh 90 days, you get a lecture, a referral back to immigration, and no exit.
The costs stack up fast. The run itself costs real money: a shared van seat runs about 1,000,000 VND, a private car more, and the Laos visa and border fees add more on top. That money is gone whether you cross or not. Then you pay the overstay fine anyway, at the same bracket you were in before, because the days kept counting while you were driving to Quang Tri. And you have burned a day on a failed trip that you could have spent resolving the overstay properly.
There is also a reputation problem. Immigration notes who tried to leave with an expired visa. A failed exit attempt reads as an attempt to dodge the system, and it can push your case toward the harsher end of the fine range or invite extra scrutiny on future visa applications.
The order that works: resolve the overstay first at the Da Nang Immigration Office, pay the fine, get your exit clearance. Only then arrange a visa run or a fresh e-visa for your next entry.
