Essential Travel & Visa Terms
1. Schengen Area

A visa you apply for online. It’s issued electronically, no embassy visit needed, and often linked directly to your passport.

A visa granted at your destination’s airport or border — but only for certain nationalities. Documents and fees are still required.
4. Transit Visa
Needed if you're passing through a country en route to another and may leave the airport or stay for a short period.
5. Biometrics
Fingerprints, facial scans, or other data used to verify your identity during visa applications or border checks.

15. Exit Permit
Some countries (like Russia or some Gulf states) require formal approval to leave the country, especially for foreign workers.
International Rules & Requirements
16. Form I-94 (USA)
