Residency and Visa Documentation
Documentation prepared
with care, submitted with confidence
Residence status applications in Japan involve detailed documentation requirements and correspondence with the immigration bureau. Having the documents prepared correctly, in the right order and with the right supporting statements, gives an application its clearest possible presentation.
What this service provides
A thorough, considered approach to documentation — for applications that matter
This service covers the documentation and correspondence involved in status of residence applications, changes of status, permission for activities outside a current status, and permanent residency applications. It is available to individuals managing their own applications and to companies handling applications on behalf of employees.
Before any work begins, we give a plain assessment of the application's prospects. If the documentation is not likely to succeed as presented, or if there are steps that would improve its position, those are identified first — not after time and effort have been spent on something unlikely to proceed well.
What you can expect
- A document checklist prepared for your specific application type
- Review of supporting statements before submission

- A plain assessment of prospects before any work begins
- Clear explanation of the bureau's processing timeline and what to expect
What makes these applications difficult
The requirements are specific, the consequences of errors are significant, and the guidance available is often incomplete
Status of residence applications in Japan involve a set of document requirements that varies depending on the application type, the applicant's circumstances, and the category being applied for. The immigration bureau's own published guidance covers the standard cases clearly. The less standard ones — changes of employer, gaps in employment history, activities outside the current status, applications from outside Japan — involve a level of detail that the general guidance does not always address.
People managing applications independently often find they have assembled most of what is needed, but are uncertain about particular documents — whether a statement is worded in a way that will be read as intended, whether supporting evidence is sufficient, or whether the application as a whole presents the situation in its clearest form.
Companies arranging applications for employees face an additional layer: understanding which documents need to come from the employer, what they should contain, and how to coordinate that with the employee's own documentation — all against the bureau's processing timeline.
The approach taken here
Documentation built for your specific application, not for the general case
Application-specific checklist
A document checklist prepared for your particular application type — not a generic list, but one that accounts for your circumstances, the category you are applying under, and the bureau's current requirements for that type of application.
Statement review before submission
Supporting statements — from employers, sponsors, or the applicant — are reviewed before submission. The review considers whether the statement says what it needs to say clearly, and whether it is likely to be read as intended by the bureau.
Prospects assessment first
Before any documentation work begins, a plain assessment of the application's prospects is provided. If there are factors likely to cause difficulty, they are identified at this stage — so the decision to proceed is made with a clear picture of what the application involves.
What the process looks like
Step by step, with the bureau's timeline as the reference point
You describe your situation
At the initial consultation, you explain your current status, what you are applying for, and your circumstances. You share any documentation you already have. No particular preparation is needed beforehand.
Prospects are assessed plainly
Before documentation work begins, a frank view of the application's prospects is provided — covering what is likely to support it, what may require additional explanation, and what the bureau's processing timeline typically involves for this type of application.
Documentation is prepared
A checklist is prepared for your application type. Supporting statements are reviewed. Documents are checked for completeness and consistency before anything is submitted. For company applications, the employer documents and employee documents are coordinated together.
Correspondence is handled
Any correspondence with the immigration bureau during the process is managed on your behalf — queries from the bureau, requests for additional documentation, and notifications of outcome. You are kept informed at each stage.
Plain language pair
在留資格 (Zairyū shikaku)
Status of residence — the category under which a foreign national is permitted to remain in Japan. It determines what activities are permitted, and for how long. Changing circumstances often require a change of status.
資格外活動許可 (Shikaku-gai katsudō kyoka)
Permission to engage in activities outside one's current status of residence — for example, part-time work by a student, or activities beyond what a current work visa permits.
永住許可 (Eijū kyoka)
Permanent residency permission — a status that removes the time limit on residence in Japan and many of the activity restrictions attached to other statuses. The application criteria are specific and the documentation required is substantial.
入国管理局 (Nyūkoku kanrikyoku)
The immigration bureau — the administrative body that processes status of residence applications, issues certificates of eligibility, and handles correspondence on immigration matters.
Fee and scope
Agreed before work begins
¥33,000
documentation and correspondence fee
The fee covers the documentation preparation, statement review, and correspondence with the immigration bureau for a single application. It is agreed in advance and does not change during the process unless the scope changes significantly — in which case this is discussed before any additional work begins.
For companies handling multiple employee applications, a separate arrangement can be discussed. The fee and scope are agreed for each batch before work begins.
What is included
- Initial consultation and plain assessment of prospects
- Application-specific document checklist
- Review of supporting statements before submission
- Consistency check across all documents before filing
- Correspondence with the immigration bureau during processing
- Updates at each stage of the bureau's process
Timelines and what to expect
The bureau sets the timeline — preparation affects how the application proceeds within it
Bureau processing: 1–3 months
The immigration bureau's processing time for most status of residence applications is typically one to three months. This timeline is set by the bureau, not by the documentation service — but a complete, well-prepared application reduces the likelihood of requests for additional information that extend it.
Document preparation: 1–2 weeks
The document checklist and statement review are typically completed within one to two weeks of the initial consultation, depending on how much is already in place and what the application type requires. You will be told clearly at the outset if this is likely to take longer.
Permanent residency: longer
Permanent residency applications involve a more substantial documentation requirement and a longer bureau processing time. The prospects assessment at the outset covers this in detail — including the eligibility criteria and what additional documentation is typically required.
On the matter of outcomes
Documentation support is not a guarantee of approval — the decision rests with the immigration bureau. What the service does is ensure that the application presents the situation clearly, completely and consistently, so that the bureau has what it needs to assess it accurately. If the prospects assessment identifies significant obstacles, these are discussed before any work begins.
Before any commitment is made
A frank assessment of your application's position, before documentation work begins
The initial consultation is designed to give you a clear picture before any fee is paid for documentation work. We look at your current status, the application you are considering, and your circumstances — and give a plain view of how the application is likely to be assessed by the bureau.
If the application as it stands is unlikely to succeed, or if there are steps that would improve its position before it is submitted, those are identified at this stage. The decision to proceed — and how — remains yours. No documentation work begins without your agreement, and no fee for that work is charged until we have established that proceeding makes sense.
What we commit to
- Honest assessment of prospects before work begins
- Fee agreed in advance, no revisions without discussion
- Updates at each stage of the bureau's process
If the matter falls outside scope
If your application type or circumstances fall outside what this service handles, you are told clearly at the earliest opportunity. Where possible, an appropriate alternative is suggested before any fee is discussed.
