There are two (2) parts of the Immigration Form, the Entry Form & the Exit Form. We
will email you both forms already completed with the proper information and when you
arrive in Mexico you will immediately proceed to the immigration booth at the
airport where the immigration officer will keep the ENTRY Part of your form and
he/she will stamp the Exit Part of the form which you will keep while in Mexico.
When you are checking in for your flight back home, you will present the Exit Part
of your form along with your passport.
