Customs & Immigration forms

Thanks for this thread. Things just keep changing and overall for the better. 5 of us are coming mid December for a week. The bigger tourist airports get the new tech faster than the smaller ones. Example land in Cancun, PV, or Cabo and at most needed the online customs form. Land in Merida and they made us fill out another customs form to go with the online one we printed. And then had to fill out immigration luggage forms and something else. So I always check before flying. I will have everyone fill out the online form for this trip.
