Central America Visa Guide | The CA-4 Agreement, Entry Rules And Extensions

Central America’s geography encourages multi-country journeys between Maya heritage sites, mountains, Pacific coastal towns and historic cities. Guatemala, El Salvador, Honduras and Nicaragua share a regional immigration framework, but their border controls and nationality-specific rules still matter.

This guide explains what the CA-4 agreement does, how to count your authorised days, how to request extensions and what to consider when crossing into neighbouring countries. The advice distinguishes a regional maximum from the actual permission issued by an immigration officer.

Entry rules were reviewed against official travel guidance on 15 November 2026. Visitors should confirm the conditions for their particular passport and itinerary before booking.

What The CA-4 Agreement Is

Guatemala, El Salvador, Honduras and Nicaragua share a regional framework known as the Central America-4 Border Control Agreement, or CA-4. It was agreed in the mid-2000s to facilitate movement between the participating countries. For eligible short-term foreign visitors, an important feature is the shared period of authorised stay rather than four independent periods of admission.

The usual maximum for eligible travellers is 90 days across the four countries. The period begins at the first entry into the area and does not start over when a traveller visits another member country. The actual period granted can be shorter, and passport nationality, immigration history and local rules matter.

The agreement is sometimes compared with Europe’s Schengen area. The analogy has limits: travellers should expect official controls at land borders and may have to obtain entry or exit stamps. Check the records required at each crossing. Permission to visit one country does not automatically override the visa requirements of another.

The Canadian government guidance explains that admission for the maximum period is not automatic and that the border officer determines the authorised stay. An expulsion from one member country can also affect admission to the remaining members. Treat the agreement as a framework for planning, not a guarantee of admission.

Who Needs A Central America Visa

Visa-free access depends on your passport and purpose of travel. Many nationalities, including holders of full British, Canadian and US passports, can qualify for short tourist stays in the region. However, entry conditions, exemptions and the length of permission can vary. A residence permit issued elsewhere may have a bearing on eligibility, but possession of one does not guarantee admission.

A particularly important change concerns Honduras. British citizens were required to obtain visas from August 2024, but Honduras restored a visa exemption for British citizens on 31 October 2026. The current UK entry guidance confirms the new position, with tourist visits of up to 90 days subject to the actual permission granted. Its guidance also describes a 30-day entry stamp and extension arrangements. Check the stamp and ask the immigration officer to clarify your authorised period rather than assuming a full 90 days.

For passports that still require visas, contact the competent consular authority before travel. Some countries recognise particular valid visas or residence permits from the United States, Canada or Europe for qualifying travellers, but these policies have conditions and are not identical across CA-4.

Do not assume you qualify by nationality alone if your passport is temporary, damaged, close to expiry or issued under a different category. Confirm whether applications can be made online, at a consulate or on arrival. Obtain written confirmation when a route depends on a special exemption.

Counting Your 90 Days

Use the date of first entry into a CA-4 country as the starting point for your travel planning. Mark each movement in a calendar and compare it with the authorised end date stamped or recorded by immigration. If the officer grants 30 days, the maximum regional framework of 90 does not mean you may automatically stay for three months.

For illustration, a visitor admitted on 1 March for a full 90 days who spends 20 days in Guatemala, 15 in El Salvador, 20 in Honduras and 25 in Nicaragua would have allocated 80 days to the four countries, leaving a nominal ten-day buffer. Actual authorised dates and the treatment of entry and exit days take precedence over an illustrative calculation.

The 90-day period does not restart at an internal border. Leaving for Belize, Mexico, Costa Rica or Panama also does not establish an automatic entitlement to a new period on return. Do not assume that an absence pauses the original permission. Confirm the effect of departure and re-entry with the authorities, especially if returning near the expiry date.

Keep a clear record of admission notices, stamps and dates. A photograph stored securely can help if the original becomes unclear, but it is not a replacement for the passport or an official immigration record. Check your documents before leaving the immigration desk.

Where the date is uncertain, seek clarification in advance rather than discovering a problem on the day of departure. A booking, airline ticket or private online day counter cannot establish legal permission to stay.

Extending Your Stay

Several CA-4 authorities provide a procedure to request an extension before the existing permission expires. Regional guidance describes extensions of up to 30 days in relevant circumstances. An extension is not automatically approved, and the procedures and documentation depend on the country in which you apply.

In Guatemala, contact the Instituto Guatemalteco de Migración. In Honduras, consult the National Institute of Migration. Nicaragua also has procedures for eligible visitors to request additional time before expiry. El Salvador’s General Directorate of Migration and Immigration handles its local extension arrangements.

Apply sufficiently early to resolve documentation issues and allow for office hours, holidays and processing. Ask whether an application receipt authorises continued presence while a decision is pending; do not make that assumption yourself. Fees, photographs, copies of identification, proof of departure and other documents may be required.

If your route involves crossing an internal border after receiving an extension, confirm how the updated permission will be recognised. Retain the official extension notice and payment receipt. If seeking a longer stay for work or study, a separate authorisation may be required rather than repeated tourist extensions.

Guatemala

Guatemala is a common starting point for journeys through Central America. Guatemala City has the principal international airport, while land routes connect the country with Mexico, Belize, Honduras and El Salvador. Antigua, Lake Atitlán and Flores are familiar places to include in a route.

The UK entry guidance describes visa-free visits of up to 90 days for eligible British passport holders. An overstay can result in a fine and considerable delays before departure. Extension applications are handled by the Guatemalan migration authority.

Check that the required entry record has been made when arriving overland. A driver or shuttle company cannot perform immigration clearance on your behalf merely by collecting your passport. If a required stamp is missing, ask the official desk for assistance before continuing.

The UK government advises against non-essential travel in specified areas near the Mexican frontier. Check the full geographic description and your actual crossing route through the official Guatemala advisory. Do not choose a route through a warned-against area to save time or money.

El Salvador

El Salvador has Pacific beaches, volcanic landscapes and towns connected by a comparatively compact road network. Its local immigration rules must still be distinguished from the CA-4 framework.

Current UK entry guidance permits eligible British visitors to stay up to 180 days in El Salvador alone. The shared 90-day CA-4 period applies to travel across the four countries. If you want to stay longer in El Salvador and then continue to another member country, ask the relevant authorities how your individual permission interacts with the regional rules.

Fees and tourist card requirements can differ by nationality and arrival point. Some nationalities have faced additional charges in the past. Verify the current charge directly instead of relying on an older tariff or a traveller’s anecdote. The US dollar is widely used for ordinary payments.

Security conditions have changed under the country’s state of exception. The authorities have broad enforcement powers, and visitors should familiarise themselves with current official safety advice, avoid restricted activity and carry identification as required.

Honduras

Honduras includes the ancient Maya site of Copán, mountain landscapes, Caribbean coast and the Bay Islands of Roatán and Utila. Those islands are part of Honduras, and the country’s immigration rules apply whether visitors arrive by sea, land or air.

Since 31 October 2026 British citizens are again eligible for visa-free short tourist visits under the latest UK guidance. Other nationalities may still need advance permission. Transit through Honduras is also subject to applicable entry requirements, even when the itinerary does not include an overnight stay.

Air connections commonly use San Pedro Sula, Palmerola International Airport and Roatán, according to airline schedules. Do not confuse the international gateway serving the Tegucigalpa area with the city’s older airport when arranging a transfer.

Consult the Honduran authorities about visa processing, documents, any digital pre-registration and possible extensions. Cruise ship arrangements may permit a limited shore visit, but visitors staying behind after departure must establish appropriate entry permission in advance.

Nicaragua

Nicaragua’s lakes, volcanic landscapes and historic cities make it a distinct part of a regional route. Managua is its principal aviation gateway, while recognised land crossings connect it with Honduras and Costa Rica.

Under the UK entry advice, eligible British travellers can visit for a period of up to 90 days, subject to the CA-4 rule. Proof of an onward ticket may be required. An extension of up to 30 days may be requested before expiry.

According to the same guidance, the cash arrival tax is USD 10, while an air departure tax of USD 35 is usually included in the ticket. Confirm how fees apply to your nationality and arrival route. Electronic smoking devices are prohibited, including devices without nicotine, and customs officers can confiscate them.

Some people, including travellers considered critical of the government, have encountered refused entry or other difficulties. Foreigners are prohibited from participating in political activity. Review the official safety information and comply with lawful immigration requirements. Do not assume that a regional agreement removes the authority’s power to refuse entry.

Belize, Costa Rica And Panama

Belize, Costa Rica and Panama do not participate in CA-4. Each has a separate immigration system, and permission for one does not establish permission for the others.

Belize commonly grants eligible visitors a 30-day initial tourist stay. The UK entry guidance describes extension fees and a departure tax for land or specified water crossings. Our Belize guide provides further context about travel through the mainland and cayes.

Costa Rica may grant eligible British tourists up to 180 days, with the final period determined on arrival. Check current documents and proof of onward travel. See the Costa Rica guide for travel planning and the official entry guidance for the applicable formalities.

Panama has its own passport rules, immigration permissions and entry requirements for sea arrivals. The UK government’s Panama advice currently describes a visa-free period of up to three months for eligible British visitors arriving by land or air, rather than six months. Other nationalities and routes have different arrangements.

The practical implication is that departing CA-4 for one of these countries requires completing the departure and arrival procedures. It does not establish a universal right to return or restart a regional stay.

Mexico And The Northern Gateway

Mexico is outside CA-4 and has separate entry requirements. A regional journey starting in Mexico and continuing into Guatemala must satisfy both immigration systems. The Mexican admission period is independent of any Central American permission.

Retain the relevant Mexican entry record and ensure your departure is properly recorded. If your itinerary returns to Mexico, confirm the conditions for re-entry and the visa rules for your nationality, including whether a multiple-entry visa is required.

Some land routes between Mexico and Guatemala pass through areas affected by serious security concerns. Read the current regional advisories and choose a lawful crossing consistent with them. Flying to an appropriate gateway may be a better option than using a route that is unsuitable under current advice.

Planning A Multi-Country Route

A north-to-south itinerary can begin in Guatemala and continue toward El Salvador, Honduras or Nicaragua, followed by Costa Rica. The best sequence depends on current land-border conditions, flights, your passport and the time you have available. The route need not include every country.

Set out intended arrival and departure dates with a buffer for delays. Allow time for border checks, transport disruptions and any requested documents. If travelling close to the end of an authorised stay, leave extra time before the deadline rather than scheduling your departure on the final possible evening.

Travellers planning extended stays outside CA-4 should check re-entry rules before purchasing return transport. Never rely on repeated short border trips as a guaranteed way to extend a tourist stay.

The North America guide provides a wider geographical perspective. Our Cuba guide illustrates another Caribbean destination that has separate entry arrangements.

Flights, Transit And Border Transfers

Regional flights may save time compared with long international bus journeys. Airports in Guatemala City, San Salvador, Managua, San Pedro Sula and near Tegucigalpa serve different networks. Check actual schedules and the airport used.

Airlines generally assess document eligibility before boarding. A valid airline ticket is not proof that the holder meets migration requirements. Transit through the United States, Mexico or another hub can require additional permission.

Even an internal CA-4 flight does not reset the shared stay period. Prepare the relevant passport and supporting documents for inspections. For overland journeys, select established shuttle or bus operators who use recognised crossings, and confirm where passengers must complete their own immigration checks.

Allow time for transfers and queues. Prefer daytime travel on suitable routes, and do not use an unofficial crossing when delays occur. Confirm the onward connection independently if the tickets are not protected under a single booking.

Tourist Cards, Fees And Payments

Some immigration authorities charge tourist cards, entry or exit levies, visa fees and extension charges. These vary according to nationality, route and current regulations. A fee collected by an airline may differ from a payment due at a land crossing.

Carry modest amounts of small-denomination US dollars and relevant local currency, together with a backup payment method. Do not assume every office accepts cards or foreign banknotes. Use authorised payment channels and obtain an official receipt for each charge.

If a charge is unclear, calmly ask the responsible official to explain the tariff or show the posted official fee. Avoid confrontations with border authorities. A reputable transport provider or your consular mission may help clarify the procedure.

The currencies of Guatemala, Honduras and Nicaragua are the quetzal, lempira and córdoba respectively. US dollars are used in El Salvador. Exchange rates and merchant acceptance vary, so do not rely on being able to pay everywhere with one currency.

Longer Stays, Business And Remote Work

Tourist admission does not automatically permit paid employment, lengthy volunteering, study or residence. Short business meetings may qualify under specific visa exemptions, but the permitted activities depend on the country and passport.

Contact the competent authority before beginning employment or enrolling in a course. A company or volunteer organisation should be able to identify the necessary permissions, but informal assurances do not replace official approval.

People working remotely should verify whether their proposed activities are permitted under their immigration status and whether a residence or remote-work scheme is available. Tax and employment obligations may also arise. Seek qualified local advice for individual circumstances.

If intending to reside in one member country, check what the residence permission means for travel to the others. Do not treat CA-4 as a regional work permit.

Children And Family Travel

Children generally need their own valid travel documents and must meet the immigration requirements applicable to their nationality. The authorised period may need to be checked separately for each family member.

Additional parental consent, birth certificates, custody documents or translations may be required when children travel alone, with one parent or with another adult. Guatemala’s current UK guidance, for example, describes a notarised Spanish-language consent letter for certain children aged 17 or younger.

Children holding local citizenship, including dual nationals, can encounter additional departure requirements. Consult the appropriate embassies and immigration offices well in advance. Carry the original or officially accepted copies of relevant documents.

Keep family members’ documents organised and verify each entry record before leaving the checkpoint. Allow extra time for questions and do not assume that permission granted to one adult covers the entire group.

Health, Customs And Safety At Borders

Yellow fever documentation may be required when arriving from countries with a risk of transmission. Requirements depend on the route and each authority’s rules. Seek advice from a qualified travel-health professional before departure and verify current health requirements for every country on the itinerary.

Customs restrictions may cover food, plants, wildlife products, medicines and electronic devices. Carry prescribed medicines in their original labelled packaging with a copy of the prescription and verify whether any require special permission. Nicaragua’s prohibition on electronic smoking devices is a particularly important difference to note.

Check official travel warnings for every country, especially along land routes. Crime, political disruption and transport conditions differ between regions. Arrive at recognised checkpoints in daylight where practical and avoid isolated transport after dark.

Use secure storage for valuables and retain offline copies of essential documents in a separate place. If a passport is lost, notify the local police and appropriate embassy or consulate and consult immigration about recording your entry under replacement travel documents. An emergency passport may not be accepted on every onward route.

Cruise Passengers And Short Visits

Cruise ships call at ports in Guatemala, Honduras and elsewhere in the region. Short visits arranged under the cruise ship’s clearance arrangements can differ from independent land or air entry. Confirm the documentation required with the operator and appropriate immigration authorities.

Passengers who plan to end a cruise in a port and continue independently need the entry permission applicable to their stay. Do not assume the short shore visit arrangement permits a longer stay.

A day excursion across a CA-4 border also involves crossing an international frontier. The short duration does not remove visa or document requirements. Make sure that both your entry and return are lawful before booking.

Common Mistakes And The Pre-Travel Checklist

The most consequential error is to assume that each member country provides a separate new 90 days. Others include relying on obsolete visa information, missing an immigration record and applying for an extension too late.

Before departure, check the entry rules for your nationality, passport validity, required visas, transit requirements and current travel advisories. Establish what documentary evidence of accommodation, sufficient funds and onward travel you may need.

During the journey, verify the actual authorised period at your first entry, complete every required border procedure, keep an accurate calendar and retain official receipts. Contact immigration early if you need additional time.

CA-4 simplifies certain regional travel arrangements, but it does not eliminate national immigration decisions. The best itinerary is one that respects the actual permissions granted and contains enough flexibility for changing conditions.
