Finn citizens can visit Vietnam for 15 days without a visa. If they need to stay longer, they can apply for a Vietnam visa through the Vietnam embassy in Finland or online. Applying online has become popular as it allows travelers to apply from home or work without visiting the embassy in person. To apply online, applicants need two passport photos and some cash for the visa fee to pay at the airport upon arrival in Vietnam. The document also provides contact information for the Vietnam embassy in Finland for those wishing to apply for a visa through the embassy.
