2. Expired Documents (Even by a Day)
Digital systems calculate dates precisely. “I thought it was valid” doesn’t matter.
How to prevent it: Put a reminder on your phone one month before your passport, visa, or FMM expires. Check expiration dates before you book travel.
3. Missing or Incorrect Tourist Permit
Mexico’s FMM is a common pitfall. Tourists often assume they don’t need it (they do). Or they misread the departure date (it’s up to 180 days, but the officer may grant less).
How to prevent it: Complete the FMM online before travel. Print two copies. Verify the authorized stay before leaving immigration.
4. Passport Validity (The 6-Month Rule)
This catches people constantly. Your passport may be valid for your trip dates, but the destination country requires 6 months beyond your return.
How to prevent it: If your passport expires within 6 months of your return, renew it before traveling.
5. Damaged Passport
A torn page, water stain, or bent cover can trigger rejection. Immigration agents in Latin America are particularly strict.
