The approach receiving authorities accept is this: the Non-B visa and the work permit are separate but linked processes: the correct visa category normally comes first, the work permit follows, and the stay extension at the Immigration Bureau comes last. Build the document timeline so one certified set supports all three stages. Note: the final decision rests with the receiving authority, so our focus is a complete and accurate document set.
