The short answer: overstaying is an administrative matter, not a criminal one, and it is priced. Costa Rica’s immigration law sets a fixed fine per month of irregular stay, and where that fine is not paid, a ban on re-entry instead.
What follows comes from the Ley General de Migración y Extranjería No. 8764 itself rather than from expat forums, because the forums get this wrong in both directions — some treat it as trivial, others as catastrophic. It is neither.
The rule you are actually breaking
Article 89, paragraph 3 puts the obligation plainly. Foreign nationals must leave the country when the period of stay authorised by the immigration authority expires — unless they have requested a change of migratory category, or been granted an extension.
Stay past that date without one of those two things in motion and you are in what the law calls estancia irregular. Irregular stay. That is the status the penalties attach to.
What it costs
The same article sets the consequence:
A migration fine equivalent to one hundred United States dollars (US$100.00) for each month of irregular stay in the country or, failing that, entry will be prohibited for a period equal to three times the length of the irregular stay.
Three things are worth drawing out of that sentence, because they are routinely misreported.
It is per month, not per day. A three-month overstay is US$300, not a running daily tally.
The ban is the alternative to the fine, not an addition to it. The law says the fine or, failing that, the prohibition. In practice the ban is what you face if the fine is not settled.
Three times the overstay is a long time. Overstay by six months and you are looking at an eighteen-month bar on returning. Overstay by two years and it is six. This is the part people underestimate, and it is the reason a small problem should never be allowed to become a large one.
What it is not
An overstay is not a criminal offence and does not produce a criminal record. It will not, on its own, prevent you from later applying for residency — Costa Rica’s law explicitly contemplates people in exactly that position, which we come to below.
It is also not a matter for negotiation at the airport counter. The amount is set by statute.
If you have overstayed and now want residency
This is the situation that brings most people to this page, and the law addresses it directly in Article 91.
Where a tourist’s maximum legal stay has expired and they nonetheless wish to apply for one of the migratory categories in the law, and the Dirección General de Migración y Extranjería judges that they meet the suitability requirements to bring that application, they may proceed — subject to the payment set out in Article 33.
There is then a clock. The applicant has ninety days to conclude the process. Once that period lapses, Article 91 says the person falls back into irregular migratory status and is again exposed to the sanctions in the law.
That ninety-day window is the detail almost nobody mentions, and it matters enormously. Filing an application does not park the problem indefinitely. It buys a defined period in which the file has to be finished.
The two legitimate ways to stay longer
An extension (prórroga). Article 90 of the Ley allows the immigration authority to extend a stay, on prior verification that you hold sufficient means to support yourself, for a fee the law sets. Read it alongside the visa directive, though: if you are in the first group and were given the full 180 days, there is nothing to extend. The extension route exists for people granted a shorter period.
A change of category from inside the country. Article 89 allows non-residents to change migratory category while still in Costa Rica, on prior payment of the fee the law sets.
Both of these are requests made before your permitted stay runs out. That timing is the whole point.
How long are you actually allowed to stay?
This is set by nationality rather than by one national rule, and it changed for the better. The current Directrices Generales de Visas de Ingreso y Permanencia para No Residentes — November 2025, published as Alcance 148 to La Gaceta No. 216 of 17 November 2025 — sorts the world into four groups.
First group: up to 180 days, no visa needed. This covers the United States, Canada, the United Kingdom and most of western Europe, along with Argentina, Australia and others. The directive sets the maximum stay at 180 días naturales — 180 calendar days. Your passport need only be valid for the period you are granted.
There is a catch in the same paragraph that matters a great deal, and it is the reason this article no longer tells you to simply extend. For the first group those 180 days are expressly no prorrogables — non-extendable. The directive permits an extension only where the officer granted fewer than 90 days, and then only up to a total of 90. If you were stamped for the full 180, there is nothing to top up.
Second group: up to 30 days, no visa, extendable to a total of 90 days. Belize, Bolivia, El Salvador, Guatemala, Honduras, the Philippines, Russia and others.
Third and fourth groups need a consular or a restricted visa, with a maximum stay of 30 days, extendable to 90.
The period granted can never exceed the validity of your passport.
180 days is the ceiling, not a promise
This is the part that catches people out, and it is worth more than any table of numbers.
The officer at the counter decides how many days you get. The directive sets a maximum. It does not entitle you to it. Within that maximum the officer has discretion, and they use it.
What they weigh up is straightforward enough:
- Onward travel. You need a ticket out. This is asked for routinely and people are refused boarding at their departure airport over it, before Costa Rica is even involved.
- Where you are staying. You may be asked to show your accommodation booking.
- Your travel history, particularly if your passport shows a pattern of long or back-to-back stays.
Here is the trap. If you show a hotel booked for one month, do not be surprised to be stamped for one month. Officers frequently grant just enough time to cover the stay you have evidenced. Plenty of people who were entitled to ask for 180 days have walked away with 30, because 30 days was all their paperwork described.
The lesson is not to be evasive — it is to make sure what you present actually matches what you intend. If you plan to be here five months, an onward ticket five months out and accommodation that reflects a longer stay will support that. A four-week hotel booking and a return flight in four weeks describes a four-week trip, and that is what you will be given.
If you are stamped for less than you hoped, note that this is the one situation where the extension route is open to you: the directive permits a prórroga where fewer than 90 days were granted, up to a total of 90.
A word on border runs
Leaving the country briefly and returning to obtain a fresh entry stamp is common practice, and it is not what the law is designed around. Admission on each entry is at the discretion of the immigration officer, who is entitled to consider your travel history. Nothing obliges an officer to grant a further full period, and people who have visibly been living in Costa Rica on consecutive tourist entries do get shorter stamps or refusals.
It is also worth knowing that Article 92 states that foreign nationals authorised to remain as non-residents may not work, save for narrow exceptions set out in the law. Living in Costa Rica on rolling tourist entries while earning here is a different and more serious problem than an overstay.
What to do if the date has already passed
- Work out the exact number of months. The fine is monthly, so the arithmetic is straightforward, and knowing the figure usually makes the problem smaller than it felt.
- Decide whether you are leaving or regularising. Those are the two routes, and they lead in different directions.
- Do not let it run. Every additional month adds another US$100 and three more months to any potential ban. Nothing about waiting improves your position.
- Get the file right before you file it. If you go the Article 91 route, the ninety-day clock starts whether or not your documents are in order.
Not sure where you stand?
Overstays are recoverable far more often than people fear, but the route out depends on how long it has been, what status you are aiming for, and what your paperwork looks like.
