How long does it take to get a visa and passport in advance to travel to Korea? Can you be more specific? There are also differences between visas and passports.

Passport is your identity card abroad. Generally, it can only be handled at the local exit-entry administration. Individual regions may be handled across regions. For details, please consult the local immigration authorities. Visa is a passport attached to the destination country, and the two concepts are completely different. The basic requirement for passport processing is 15 working days, depending on local conditions. It takes 7- 15 working days to apply for a Korean tourist visa, and materials need to be prepared. So you can apply for a passport at least two months before your trip. In addition, if you go to Korea for some plastic surgery, you can't apply for a tourist visa ~
