The answer first
LES A lists foreign passports and specified emigrant evidence; Paradise also has a separate Jeju document section. Check the applicable identity and branch. Nationality, emigrant status and document validity can alter conditions, so there is no single answer for every person.
Check before travelling
A hotel confirmation, passport photograph or another branch's table does not establish acceptance. Check the operator domain and applicable section. This site summarizes public rules, collects no passport scans and neither reviews nor guarantees eligibility.
Share only the minimum needed to explain a rules question. Keep complete passports, room numbers and companions' identification out of public comments and unfamiliar accounts. If formal verification is needed, establish the recipient, purpose and handling before deciding how to supply records.
