I am USA citizen living in South Korea, I would like to Apply for China Visa

Hi William! I'd like to give you some information.
1. You can't apply online, but you can apply by sending a package to the CVASC office there. Of course, the cost is more expensive if you apply by posts.
2. If you want to submit the application in person, you need to go to any of the CVASC office in SK.
3. Apart from the passport, you need to submit a photocopy of the passport, an application form, a recent bare-headed photo, the original and photocopy of your ARC card, and documents that can prove your visit purpose.
4. There is no template for the invitation letter.
