If things go wrong

Overstay, refusal & deportation in Cambodia

ModerateEnforcement posture

Overstay fines

Cambodia typically charges a per-day overstay fine payable on departure. Short overstays may be waived at officer discretion, but the published amount is set by the immigration authority.

Visa rejection consequences

A refusal or denied entry can usually be re-attempted later with stronger documentation, but it must be disclosed on future visa forms that ask.

Re-entry bans

Re-entry bans are uncommon for short overstays settled at departure, but repeat or long overstays can trigger multi-year bans.

Deportation risks

Formal deportation is reserved for serious overstays, illegal work, or criminal offences — most overstayers simply pay the fine and leave.

Penalties change frequently and vary by circumstance — treat this as a planning guide, not legal advice. Settle any overstay or status issue with the local immigration authority before departure where possible.

Extensions & visa runs in Cambodia

Usually yesCan you extend your stay?

Cambodia has a pragmatic posture toward visitors who play by the rules and apply for extensions properly.

How many times?

Cambodia routinely grants in-country extensions. Apply at the immigration office before your stay expires; the exact length is set by the immigration authority.

Visa run rules (leave & re-enter)

Cambodia actively monitors back-to-back entries. Border officers can refuse re-entry, shorten the stay granted, or impose a mandatory cooling-off period after repeated short trips.

Border discretion is real — even when extensions are technically allowed, individual officers can refuse. For stays beyond a few months, switching to a proper long-stay, student, or remote-work visa is almost always safer than repeated runs.
