What documents does Xi 'an need to apply for a tourist visa to Korea?

If it's just a short-term tour, you can join a group, so don't bother, because it's difficult to get a visa in Korea now. If you travel alone, you should need the following items:

Original valid passport, copy of the front and back of ID card, copy of the whole household registration book, bank deposit certificate, and deposit of 30,000 yuan or more.

You can go to the embassy and ask what else you need, so as not to add additional conditions now.

I hope it helps you.
