Comprehensive Support for International Marriages, Spouse Visas, and Dependent Visas

Immigration procedures for international marriages—such as “Spouse or Child of Japanese National” or “Spouse or Child of Permanent Resident”—require extensive evidentiary documentation and specialized legal knowledge.

Our office provides total, end-to-end support for internationally married couples, ranging from initial spouse visa applications to future permanent residence applications, as well as visa renewals and changes for foreign nationals living in Japan.

Leave complex explanation letters, relationship proof documents, and coordination with the Immigration Bureau entirely to us to ensure a secure and reliable visa acquisition.

STEP 1

Free Consultation & Advice

We will briefly understand your current situation (qualifications, issues, etc.). You can send messages in your native language using translation tools. Feel free to contact us 24 hours a day.

STEP 2

Hearing & Estimated Cost Proposal

We will propose the best visa plan tailored to your situation. In addition, we will provide a detailed cost estimate clearly stating the “total cost required (service fee + government fees)”. There are no hidden or extra charges, so you can rest assured.

STEP 3

Contract & Payment

Once you agree with the estimated cost, an official contract will be made. You can choose a flexible payment method according to your budget.

■ About Payment Methods
  • If the service fee is less than 1 million yen (100,000 JPY): Full payment at the time of contract.
  • If the service fee exceeds 1 million yen: You can choose either “Full payment” or “Two installments (50% upfront / 50% upon visa approval)”.

※If your visa is refused for any reason, we will investigate the cause and assist you in reapplying once free of charge.

STEP 4

Document Preparation

Our office will prepare the necessary documents for your visa. We will also provide a list of documents you need to prepare and assist you smoothly. Since the “Statement of Reason” submitted to the Immigration Bureau is extremely important for the visa, we will professionally craft an effective document.

STEP 5

Submitting Application to Immigration Bureau

An Administrative Scrivener (Gyosei-shoshi) will submit the application to the Immigration Bureau on your behalf. You do not need to visit Immigration, allowing you to focus on your work or studies. Even if the Bureau has any questions or instructs you to submit additional documents, our office will handle everything.

STEP 6

Result Notification & Completion

The result will usually come out within about 1 to 3 months after application. The process is complete once you receive your new Residence Card!
※The time may take a little longer due to reasons such as submitting additional documents, but our office will provide full support quickly and reliably until final approval is granted.

Q My Japanese is not very good. Can I still consult with you? +

Yes, absolutely no problem. At our office, we utilize translation tools and message exchanges via LINE to create an environment where you can comfortably communicate in your native language. In addition, we also support communication in simple Japanese or English, so please rest assured.

Q What should I prepare when coming for a consultation? +

For individual clients, having your “Residence Card” (Zairyu Card) and “Passport” ready will help us provide more specific and smooth advice. For corporate clients, it will be very helpful if you can prepare the resume of the prospective employee or company profile information.

Q As a company wanting to hire foreign nationals, where should we start? +

First, we will listen to the details of the planned job description and the candidate’s background (education, work experience) to provide a free diagnosis on what type of visa can be applied for and whether the requirements are met. Even if you are just at the stage of “wanting to hear about it first,” please feel free to contact us.

Q What is your supported area? Do I have to visit the office for a consultation? +

Our main supported areas are Chiba Prefecture (Togatsu and Northwest regions), Tokyo (Eastern area), and Saitama Prefecture (Eastern region).
Visiting our office is not mandatory. If preferred, we can directly visit your home, company office, or a nearby café to discuss.
In addition, we support online meetings via Zoom, as well as consultations via LINE and email, so you can use our services from anywhere nationwide. We also accept evening consultations after work hours or on weekends by prior appointment, so please let us know the method most convenient for you.

Q I applied by myself and got refused (Fuhyoka). Can your office help handle it? +

Yes, we do handle it. We will accompany you or check with the Immigration Bureau, analyze the reason for refusal in detail, and then propose the optimal plan for reapplication. (We also have a “Free Reapplication Guarantee” policy, where if an application accepted by our office is unfortunately refused, we will assist in reapplying once free of charge without additional service fees).

Q Can the service fee be paid in installments? +

Yes, if the remuneration exceeds 100,000 Yen, you can use flexible payment methods such as “Two-stage payment (50% deposit upon starting + 50% upon visa approval)”. We will provide a clear total cost estimate in advance, so rest assured that there will be absolutely no obscure additional costs afterwards.

Q Can I temporarily leave the country (return home) while waiting for the application review? +

As long as you are still within the validity period of your current status of residence, it is basically possible to return home temporarily by using a special re-entry permit. However, there are points to note depending on the timing of the procedure and review status, so please be sure to consult with us in advance.

Q Do I have to sign a contract after a consultation? +

No, we never engage in aggressive sales or force unnecessary contracts. Inquiries such as “I am wondering whether to try doing it myself” or “I just want to check if I meet the requirements” are very welcome. Even if you choose to proceed with the procedure on your own, we will kindly advise you on the necessary steps and precautions.

Q I have received a quote from another administrative office. Can we discuss the fee? +

Yes, please feel free to discuss it with us. At our office, alongside aiming for meticulous and high-quality support, we always strive to make flexible proposals tailored to our clients’ budgets and situations.
If you show us the price quote or proposal contents from another office, we will check whether our office can provide equivalent or better support at a reasonable price, and we will do our best to provide a quote that matches your expectations. Inquiries such as “I just want to compare costs” are also welcome.

Q How long does it take from application until the result comes out? +

It depends on the type of status of residence and the congestion status at the Immigration Bureau, but it generally takes about 1 to 3 months from the application date to get the result. Taking into account the preparation period for necessary documents (about 1 to 2 weeks), we recommend consulting early, such as 2 to 3 months before your period of stay expires, to ensure a relaxed schedule.

Q What is the difference between documents prepared by myself and documents prepared by an Administrative Scrivener (Gyosei-shoshi)? +

Public documents obtained from administrative agencies or companies, such as Resident Tax Certificate (Juminhyo), Tax Payment Certificates, and company financial statements, must be prepared by you (we also offer acquisition assistance). Our office will take charge of creating the “Statement of Reason” which greatly influences approval or rejection, as well as drafting application forms, thoroughly checking various certificates, and compiling all documents for submission to the Immigration Bureau.

Q Can I apply for family visas (Dependent visa, Spouse visa, etc.) at the same time? +

Yes, of course you can. You can entrust your family’s (spouse or children) visa procedures together with your own work visa or permanent residence application. By requesting them simultaneously, you can reduce duplicate supporting documents and proceed smoothly.

Q What happens if the visa is unfortunately “refused”? +

Although we conduct thorough eligibility diagnostics before taking on a case, if a refusal unfortunately occurs, we will reapply once free of charge without additional costs (Free Reapplication Guarantee). In addition, we will accompany you to the Immigration Bureau to accurately identify the reason for refusal and propose the best countermeasures to turn the situation around.

Q I am an international student. Can I consult about finding a job or starting a business in Japan after graduation? +

Yes, we would be delighted to support you. Not only for changing to a “Engineer / Specialist in Humanities / International Services” visa once a job offer is secured, we also propose the optimal visa type according to your future career path, such as a “Business Manager” visa if you want to start a business in Japan, or a “Designated Activities” visa to continue job hunting.

Q What is the procedure flow after officially entrusting the office? +

After you agree with the consultation details and quote, the flow is as follows: ① Formal contract and deposit payment → ② Guidance on required document checklist from the office → ③ Document preparation and verification → ④ Application submission to the Immigration Bureau (handled by the office on your behalf) → ⑤ Result notification and delivery of the new residence card. As a rule, clients do not need to queue at the Immigration Bureau counters.

Q My period of stay has expired and I am in an overstay (illegal stay) status. Can I still consult? +

Yes, please consult as early as possible before it is too late. Leaving an illegal stay status as-is is extremely dangerous, but by voluntarily appearing and proceeding with procedures (such as applying for a Special Permission to Stay / Tokkyo, or return procedures), we can find the best solution depending on the circumstances.
We will sincerely confirm legal options based on your family situation and living foundation in Japan. All information will be kept strictly confidential, so please do not worry alone—feel free to contact us right away.
