THIS IS A MESS. The WEB is littered with persons who have failed to complete this form. Here are some points: (1) It appears that the form is mandatory for all entrants, regardless of nationality, (2) There are sites that you can pay to process the form such as
colombia-checkmmig.com Of course, the price is hiddent until you complete the form; $35.00 per person. I can't prove it but this strongly smacks of fraud and I refuse to pay, (3) It appears that the form is called Check-MIG Colombia or in Spanish "formulario check-mig Colombia.", (4) I found many suggested links to variations of the official site and they all returned 404 errors, (5) Here is the failure (for me): Page 2 of 5: ?De que ciudad viene el vuelo? ; Digite la ciudad; Debes seleccionar tu ruta. When you try to input your city, regardless of what you input, SDQ, Santo Domingo, PTY, it initiates a drop-down menu. The drop-down menu will not populate, so you cannot select. Neither can you enter a city manually. With that field blank, you cannot continue, (6) If they refuse to let us board, I'm going to make a scene. and be very aggressive, insisting that I sort this with Colombian immigration upon my arrival. I have two pages of error messages and a return email from the officiaal site whose help link failed, (7) I found a YouTube video from "somebody" who said that the site was not functioning and that you need to communicate directly with immigration personell. Low credibility on that--not a government official, just somebody. I bought no refund tickets from Expedia and went to customer support. They cannot help and have no advice.
