Do I need a health certificate to go abroad to Korea for the first time?

Hello, as this is the first time to go abroad, I strongly recommend that you apply for a health certificate. In theory, you need to show your health certificate when you go abroad, but at present, you don't check this matter very much. Although I don't check it often, I sometimes ask for a health certificate. It doesn't cost much to get a health certificate, and it is very convenient. I suggest getting one, so as to avoid going abroad.
