Define your situation
Start with your nationality, intended length of stay and purpose: tourism, study, work, family or another project. These factors determine which requirements you need to examine.
Prepare your documents
Check passport validity, information entered in applications and any supporting documents that may be required. Keep secure digital copies of important documents.
Check again before departure
Administrative rules can change. Before making non-refundable purchases or travelling, confirm the current requirements with the relevant official authorities.
