What does the entry requirements tool cover?
The tool summarizes the main rules for each country. Here are four rules that matter on almost every trip, and what official sources say about each.
Passport Validity
There is no single rule for the whole region. For U.S. citizens, Costa Rica asks for a passport valid for the length of your stay, Panama for at least three months beyond arrival, and Honduras and Nicaragua for six months. Keeping six months of validity beyond your entry date meets the strictest of these rules, so it is a safe benchmark. The table below lists every country.
CA-4 Border Agreement
Guatemala, El Salvador, Honduras, and Nicaragua operate under the Central America-4 (CA-4) Border Control Agreement. Once you enter any one of them, you can move among all four on a single shared stay of up to 90 days, without needing a separate visa for each country. The immigration officer at your first point of entry sets the exact number of days, and moving between the four countries does not restart the clock. Leaving the four-country region is what starts a new allowance, and re-entry is always at the officer’s discretion. Belize, Costa Rica, and Panama are not part of the agreement and keep their own limits.
Onward Ticket (Proof of Onward Travel)
Costa Rica, Panama, and Nicaragua all list a return or onward ticket as an entry requirement in U.S. State Department guidance, and the U.S. Embassy in Belize says visitors need proof that they intend to leave. Costa Rica’s tourism board accepts a pre-purchased flight or bus ticket out of the country, or proof of passage on a cruise ship. If you are traveling overland with no fixed date, sort out your exit ticket before you go.
Health and Vaccination Requirements
There is no blanket vaccine requirement for Central America, but a yellow fever certificate can be mandatory depending on where you are arriving from. Costa Rica and El Salvador require it if you arrive from certain countries in South America or Africa. Honduras also counts Panama and every country in South America. Nicaragua applies the rule to travelers who visited or transited at-risk countries in South and Central America or Africa, and the shot must be given at least 10 days before travel. Guatemala requires no vaccinations. Panama’s sources differ on whether the certificate is still mandatory, so carry your yellow card if you have been in a risk country and confirm with your airline.
Passport and yellow fever rules by country

| El Salvador | Valid at the time of entry | Required if arriving from certain countries in South America or Africa |
| Guatemala | Valid at the time of entry; no minimum period for U.S. passports | Not required |
| Honduras | Six months beyond your arrival date | Required if arriving from Panama or any country in South America |
| Nicaragua | At least six months, and for the entire stay | Required if you visited or transited at-risk countries; shot at least 10 days before travel |
| Panama | At least three months beyond your arrival date | Sources differ; carry the certificate if you have been in a risk country |
Avoid setbacks on your adventure
Immigration policies can change without prior notice, so treat any summary, including ours, as a starting point.
Confirm the current rules with the embassy or consulate of your destination before you fly, and check each country’s migration website for entry fees and online forms. Guatemala, for example, requires an electronic immigration form to enter and exit, and Nicaragua collects a $10 cash tourist entry fee on arrival. Optimize your itinerary and make sure you comply with all local laws before boarding your flight or crossing a land customs checkpoint.
