I want to apply for a three-month single-visit visa to Korea.

Yes, there are two ways to apply for a Korean visa:

One is to entrust a qualified travel agency, and the other is to let the applicant go to embassies and consulates in China.

These two methods have their own characteristics. Travel agencies need fewer procedures, but they need to pay a certain refund deposit, and the success rate is higher than that of individuals going to embassies and consulates.

Applicants who submit their own materials to the embassy or consulate need more materials. Although they don't accept a refund of the deposit, they are more likely to be refused visas than applicants who submit materials from travel agencies.

It depends on which consular district you belong to. If you are close to the embassy or consulate and have good personal information, you can choose to go to the embassy or consulate in person, otherwise it is better to entrust a travel agency to handle it ~
