Exiting Laos with an expired visa is not advised and may result in issues. Unlike Vietnam, where you may pay penalties and acquire an exit visa to depart legitimately, Laos has harsher overstay laws. Here’s what you should know:

Consequences of exiting Laos with an expired visa:

Fines: You will almost certainly be fined for each day you overstayed. The precise fee varies according on the length of your overstay and can range between $10 and $200 each day.
Detention: In exceptional situations, particularly for large overstays, immigration authorities may hold you until the problem is resolved. This may entail paying the penalty, arranging for an onward journey, and maybe incurring further penalties.
Blacklisting: Overstaying or breaking immigration restrictions on many occasions may result in being barred from entering Laos in the future.

Alternatives to exiting with an expired visa:

Visa extension: If you notice your visa is set to expire before your intended departure, you can ask for an extension at a Laos immigration office. However, extensions are not guaranteed and will incur expenses. While you have a Laos eVisa, you can stay in Laos for up to 30 days Per Entry.
Border run: Some visitors attempt a “border run” to another country and then re-enter Laos with a new visa. While it may appear to be a quick treatment, it is dangerous and not always successful. If immigration officials think you are attempting to bypass visa requirements, they may deny you re-entry.

In addition, you should know some tips for traveling to Laos to have a perfect trip:

Always check the validity of your visa before traveling to Laos.
Plan your trip carefully and make sure you have a valid visa for the duration of your stay.
If you know your visa is about to expire, you should move fast and look into options like as extensions or border runs.
