Reference to this question: Do I need a visa to transit through South Korea? It is not clear that can I spend my time outside the airport? I'm Indian national with valid passport till 2024, valid US visa (business B1) and have ticket back from USA to India. I'll transit in Incheon for close to 20 hours. So this my return trip from USA to India.
Am I allowed to transit without visa ? Am i allowed to go outside the airport?
