Yes, you can apply for a Mexico eTA before your travel plans are fully confirmed, but your application must include your intended travel dates.
What You Need to Know
The Mexico eTA application requires you to provide an estimated arrival date. While you do not need a fully booked ticket or confirmed itinerary to apply, the eTA will be submitted to the government based on the travel dates you provide. sherpa° can hold your application and submit it at the appropriate time closer to your travel date to help ensure it aligns with your plans.
Our Recommendation
If your travel dates are not yet final, apply early through sherpa° with an estimated arrival date. This approach helps avoid last-minute issues and ensures timely processing.
A Quick Tip
Keep your travel dates as accurate as possible when applying and notify sherpa° of any changes so your eTA is submitted at the right time.
