Trip timing
When should you start a visa or travel-authorisation application?
How to plan around eligibility windows, government processing, passport renewals, document collection and changes to an itinerary.
There is no universal lead time
Application windows and processing guidance vary by destination and document type. Some systems accept applications months before travel; others are designed for a shorter period. Always use the current official instruction for your document.

Check requirements before non-refundable bookings
Confirm the likely document route before committing to travel that cannot be changed. Approval and processing time are controlled by the relevant authority, not by eVisa Immigration, an airline or a travel agent.

Resolve passport issues first
Check passport validity, condition and blank-page requirements before applying. If renewal is likely, determine whether an approval will be linked to the old passport and whether a new application would be required.

Build a realistic buffer
Allow time to collect records, correct errors and respond to requests. Published processing guidance is not a guarantee, and exceptional checks, peak periods or incomplete submissions can take longer.
- Identify the official application window.
- Check the passport before starting.
- Collect documents before entering a timed form.
- Leave time for follow-up requests.
- Recheck entry rules shortly before departure.

Recheck after important changes
A new passport, revised route, different travel purpose or changed personal circumstances may affect an application. Use the authority's update process where one exists and do not assume an old approval covers new details.
