Colombia Check-MIG Deadline – When to Submit Your Form 2026
Timing your Colombia Check-MIG submission correctly is critical. Submit too early and the system won’t accept it. Submit too late and you risk boarding problems. This guide explains exactly when to complete Check-MIG and how to plan your submission for different flight scenarios.
For the complete overview, see our Colombia Check-MIG guide.
The 24-Hour Rule
Colombia’s Check-MIG system operates on a strict 24-hour window. You can only submit the form within the 24 hours immediately before your scheduled arrival time in Colombia.
- More than 24 hours before arrival: ❌ System rejects submission
- Within 24 hours before arrival: ✅ Accepted
- After arrival: ❌ Too late – should have been done before boarding
Important: The 24-hour window is measured against your arrival time in Colombia, not your departure time from your home country.
Optimal Submission Times
- Best: 12-20 hours before Colombian arrival
- Good: 6-12 hours before arrival
- Acceptable: 2-6 hours before arrival
- Risky: Less than 2 hours before arrival (leaves little margin for errors)
Practical Examples
Morning Flight (Miami to Bogotá)
- Departs Miami 08:00, arrives Bogotá 11:00
- Complete Check-MIG: Previous evening around 20:00-23:00 (12-15 hours before arrival)
Long-Haul Flight (London to Bogotá)
- Departs London 14:00, arrives Bogotá 20:00 (next day)
- Complete Check-MIG: The day of departure, around 20:00 (24 hours before Colombia arrival)
Red-Eye Flight (New York to Bogotá)
- Departs New York 22:30, arrives Bogotá 05:00
- Complete Check-MIG: That afternoon/evening, around 17:00-20:00
What If Airlines Check at Check-In?
Many airlines now verify Check-MIG completion at check-in. Without your QR code, airlines may:
- Require you to complete it before issuing your boarding pass
- Deny boarding if the form cannot be verified
- Allow you to complete it using airport Wi-Fi (not guaranteed)
Always complete Check-MIG well before arriving at the airport.
Set a Reminder
Set a phone reminder for 18-20 hours before your Colombian arrival time. This gives you plenty of time to complete the form and fix any errors or technical issues. You can also complete it in the 10-15 minutes it typically takes.
Can I Submit Multiple Times?
Yes. If you make a mistake, submit Check-MIG again with correct information. The most recent valid submission is used by immigration. There is no penalty for multiple submissions within the 24-hour window.

Frequently Asked Questions
Can I fill out Check-MIG 48 hours before my flight?
No. The system only accepts submissions within the 24-hour window before your scheduled arrival in Colombia. Earlier submissions are automatically rejected.
What if I miss the Check-MIG deadline?
You may be able to complete it at the departure airport before check-in. Some Colombian airports have on-arrival assistance, but this is not guaranteed and may cause significant delays. Always complete it before leaving for the airport.
Is the 24-hour window measured from departure or arrival?
From your arrival time in Colombia. This is especially important for long-haul flights where departure and arrival fall on different days.
Can I fill out Check-MIG on the plane using in-flight Wi-Fi?
Technically possible if within the 24-hour window and Wi-Fi is available, but not recommended as in-flight Wi-Fi is unreliable. Always complete Check-MIG before boarding.
