Can I enter Mexico or the Caribbean with less than 6 months on my passport?

Mexico's official requirement is passport validity for the duration of your stay, but many airlines enforce the 6-month rule and won't let you board. Most Caribbean islands require 6 months validity as official policy. Don't risk it — renew your passport before booking if you're cutting it close.

What happens if I lose my FMM form in Mexico?

You'll need to visit an immigration office (INM) before departure to get a replacement, which involves paperwork, possible fees of $50-80, and potential delays. Keep your FMM stapled in your passport and photograph it as backup. Hotels sometimes accidentally collect it with your passport — always check before checkout.

Do I need a visa if I'm just connecting through Mexico to another country?

If you're staying airside and not passing through immigration, no visa or FMM is needed. If you're collecting bags and re-checking them, or leaving the airport even briefly, you must go through immigration and get an FMM like any other visitor.

Can I extend my stay once I'm in Mexico or the Caribbean?

Mexico allows extensions at INM offices but the process is bureaucratic and not guaranteed. Most Caribbean islands allow extensions through immigration departments for fees of $50-150, granted at their discretion. Easier solution: leave and re-enter if your travel plans allow, but check if there are limits on how quickly you can return.

What's proof of sufficient funds and will immigration ask for it?

Immigration officers can ask to see that you have money to support yourself — usually around $50-100 per day of your stay. A bank statement, credit cards, or cash can work. In practice, having a return ticket and looking like a normal tourist means you're rarely asked, but have a credit card visible just in case.

How to Handle Entry Requirements for Your First Trip to Mexico or the Caribbean

Most US, Canadian, and EU citizens don't need a visa for Mexico or most Caribbean islands for stays under 30-90 days, but you do need a passport valid for at least 6 months beyond your travel dates. You'll fill out immigration forms on the plane or at arrival, and some destinations charge tourist fees or require proof of onward travel.

Check if you need a visa for your specific destination. Mexico and most Caribbean islands offer visa-free entry for US, Canadian, and EU passport holders for tourism stays of 30-180 days depending on the country. Check your exact nationality and destination pairing. Cuba requires a tourist card (visa) for most travelers. Dominican Republic requires a tourist card but it's often included in your airfare. British territories like Turks and Caicos generally follow UK visa policies.
Verify your passport validity. Your passport must be valid for at least 6 months beyond your planned departure date from the region. Mexico technically requires only validity for the duration of stay, but airlines often enforce the 6-month rule. Check the passport has at least 2 blank pages for entry and exit stamps.
Gather proof of onward travel. Most Caribbean islands and Mexico require proof you're leaving before your authorized stay expires. Print your return flight confirmation or have it accessible on your phone. If you're island-hopping, have your next confirmed flight or ferry booking ready to show. Immigration officers can and do deny entry without this.
Complete your immigration form. For Mexico, you'll receive a Forma Migratoria Múltiple (FMM) on the plane or at the border. Fill it out completely and keep the stamped half in your passport — you'll surrender it when you leave. Some Caribbean islands use paper forms, others use electronic systems. Complete the form accurately with your accommodation address and expected departure date.
Prepare for tourist fees and taxes. Dominican Republic charges a $10 tourist card (usually in your ticket price). Mexico's FMM fee is around $30-35 (also typically included in airfare, but confirm). Some islands like Antigua charge departure taxes not always included in tickets. Have a credit card ready at immigration counters just in case.
Know your authorized length of stay. Immigration officers in Mexico can grant anywhere from 7 to 180 days — check the number written on your FMM form immediately. Most Caribbean islands grant 30-90 days automatically. The stamp or form tells you when you must leave. Overstaying can result in fines of $30-50 per day or entry bans.
