Online booking, it's cheaper to fly from Hong Kong to San Francisco with a transit in South Korea. It's said that a transit visa is required. Is it to apply for it directly at the airport in South Korea or should it be done in advance in China? Do you know ?

Fly from Hong Kong to San Francisco, and even a direct flight is only more than 5000, why do you need to stop at one station? How much can you save?
The same airport, visa-free.
Surely it's more convenient to handle it domestically with HTML tags retained.
