Full answer
Start at the official embassy or consulate website of the country you're visiting — not a third-party site. Identify the correct visa category (tourist, business, student, work) because requirements differ substantially between types.
Common documents required include a valid passport (usually with 6 months of remaining validity beyond your travel dates), passport-size photos meeting specific dimensions, a completed application form, proof of accommodation, return flight itinerary, bank statements showing sufficient funds, and travel insurance.
Many countries now offer e-visas that can be applied for entirely online. You upload documents, pay by card, and receive an approval by email. These are faster and cheaper than traditional embassy appointments.
Processing times range from 24 hours for e-visas to 3 months for some work visas. Apply well in advance — at least 6–8 weeks before travel for embassy applications. Track your application through the official portal and keep the reference number safe.
