When you leave the US or Canada for your vacation in Mexico, be prepared to fill out Customs and Immigration forms. It is helpful to know what these forms look like and what questions you will be asked.
The first two scans are your FMM, or Tourist Visa. You will be given this form to fill out while on the plane before you arrive to Mexico. This is a simple form that just requires the info directly off your passport.
When you arrive to Cancun International Airport, the first stop after getting off the plane will be at Immigration. Here the immigration officer will take the FMM form you filled out, keep the blue side and give you back the green side. The blue side is your Entry into Mexico and the green side is your departure visa when you leave Mexico. It is VERY IMPORTANT to keep the green part (with your passport) as you MUST have this to leave Mexico. What happens if you lose your FMM Tourist Visa while in Mexico. Every person must fill this out.
Also during your flight to Mexico you will be given a Customs Declaration form. Each head of household needs to fill this out. Again it asks for your basic passport info, how long you will be in Mexico, and how much luggage you have. Most importantly it asks if you are carrying 10,000 US Dollars or more, any meat, food, plants, chemicals, weapons, or merchandise for which you need to pay duty.
After you land and clear immigration, your next stop will be to pickup your luggage and go to customs. Your luggage will go through x-ray and you will hand the customs agent the form. There is a button that each person must push. If the button light turns green then you proceed to pickup your scanned luggage. If the button light turns red, your luggage will be searched.
When you leave Mexico you will surrender your FMM Tourist Visa and you will fill out the US Customs Declaration form. The US wants to know about your travel, where you’ve been and where you are going. The form asks again if you are bringing cash, meat, plants, merchandise, etc. You will give this form to the Customs agent when you land in the US.
