After you plane lands in Mexico, you are
directed through the airport to line up to clear customs.
Have your passport and Identification (ID) as well as your
Tourist Form (FMM) and Customs declaration form
(below) ready for the agents. When you reach
the head of the line you are confronted with what appears to
be a large traffic light; Red and Green but no Amber.
Each person is required to press a large button to randomly
pick which lamp lights. If it turns Green you are
allowed to pass without inspection, and you have made it into
the country hassle free. If it goes Red, you are
directed to a side counter where you are questioned and your
bags are checked. You will normally still clear in a few
minutes unless drugs, concealed weapons, or any items thought
to be for resale are found. Be careful what personal
items you pack, as you may have to show them to custom agents.
If you have an unusual amount of luggage or oversized bags,
you may be automatically flagged for inspection. Make
Prescription Drugs are in their original containers, as
Mexico has a zero tolerance for drug smuggling.
