noun
special re-entry permit
A legal term in Japanese immigration law. Refers to a system that allows foreign residents to leave Japan temporarily without obtaining a conventional re-entry permit, provided they return within a certain period (usually one year).
みなし再入国許可を利用すれば、出国前に再入国許可を取らなくても日本に戻れます。
If you use the special re-entry permit, you can return to Japan without obtaining a re-entry permit before departure.
再入国許可 is the general term for a re-entry permit, which usually requires a separate application. みなし再入国許可 is a special type that is automatically granted under certain conditions.
Compound of みなし (deemed, regarded as) + 再入国許可 (re-entry permit). The term reflects the legal fiction that the permission is considered granted without a formal application.
