What this document is
The dispatch agency pledges four things to Immigration: ① nothing declared is false · ② it has explained to YOU and to the HOST COMPANY what Engineer status allows you to do · ③ it will cooperate when Immigration asks for extra documents, calls you in for questioning or carries out an on-site inspection — and the host company agrees to the same · ④ it will do all of this again whenever the host company changes.
What it must show
- Immigration's reference form (参考様式), headed 「所属機関（派遣元）用」
- YOUR NAME in the 申請人氏名 field and the status applied for (技術・人文知識・国際業務)
- Date · company name · representative's name · name of the person in charge
- Signature + company seal (社印)
Where to get it
The HR department of the dispatch agency (派遣元) — where you signed your employment contract and get paid. The quickest way is to download the form and hand it to them.
Notes
This is mandatory under Immigration's new notice. Without it the application does not meet the requirements.
