Quick answer: For most people, the right first contact is a licensed 行政書士 (gyoseishoshi / immigration lawyer-adjacent specialist) or an immigration consulting firm that files Certificate of Eligibility (COE) applications on your behalf — not the Immigration Services Agency directly, and not a general-purpose lawyer unless your case involves litigation. Who exactly you need depends on whether you're applying from overseas, already in Japan, or sponsoring someone else's application.
Why this question is harder than it sounds
Quick answer: "Visa help" actually splits across several different professionals and institutions depending on what stage you're at, and contacting the wrong one is the single biggest reason people lose weeks on their COE timeline.
A COE isn't a visa — it's a pre-clearance document issued by Japan's Immigration Services Agency (ISA) that your local embassy then uses to issue the actual visa stamp (we break the document itself down in what a Certificate of Eligibility actually is). That two-step structure is exactly why people get stuck: the ISA doesn't provide case-by-case guidance to individual applicants, embassies only handle the final visa stamp (not COE strategy), and general immigration "consultants" advertising online range from fully licensed 行政書士 to unlicensed agents who can't legally file on your behalf at all. If the distinctions between Japan's licensed professions are new to you, gyoseishoshi vs shihoshoshi vs zeirishi vs sharoushi covers who is allowed to do what. Knowing which door to knock on first saves most of the delay.
Who can actually help, by situation
Quick answer: Match your situation to one of four contact types below rather than searching generically — it's the fastest way to avoid a dead-end conversation.
You're an individual employee or founder applying from overseas. A licensed 行政書士 or immigration-focused firm is your primary contact. They can assess visa category eligibility (Engineer/Specialist in Humanities, Business Manager, Startup Visa, etc.), prepare and file the COE application with your sponsoring organization in Japan, and track the application through ISA review — typically 1–3 months depending on category and region.
You're a company sponsoring a foreign hire or transferee. The same specialist firms handle this, but the intake conversation is different — they'll need your company's registration documents, the role's job description, and compensation details to build the sponsor-side case. This is usually where things stall if a company tries to self-file without prior COE experience. If the sponsoring entity itself still needs to be incorporated, or its corporate registry updated first (new director, capital increase, registered address change), that's technically a separate 司法書士 (judicial scrivener) task — firms that keep scriveners in-house, ours included, can generally run the incorporation and COE workstreams in parallel rather than sequentially, which is often where a few weeks get saved.
You're already in Japan and need a status change or renewal. This routes through the same 行政書士 channel, but timing matters more — renewal applications are generally submitted within about 3 months of expiry, and status-change applications (e.g., Startup Visa to Business Manager) need the receiving visa category's requirements fully in place before filing, not after.
Your case involves a denial, appeal, or legal dispute. This is the one scenario where you want an immigration attorney (弁護士) rather than a 行政書士 — license scope differs, and only attorneys can represent you in formal appeals or litigation.
What to have ready before you reach out
Quick answer: Contacting the right person still wastes time if you show up without basic facts — passport nationality, intended visa category, sponsoring entity (if any), and rough timeline are the four things any competent firm will ask first.
Firms that handle COE filings professionally will typically ask for this before giving you a real answer rather than a generic "it depends." If a firm gives you a category and timeline estimate on the first call without asking any of this, that's usually a sign they're not looking closely at your actual case. Some firms — ours included — now run this intake step through a structured platform like BizJapan AI rather than a back-and-forth email chain, partly because COE filings involve enough recurring documentation (proof of funds, business plans, employment contracts) that a shared tracking system beats a scattered inbox. If you're evaluating firms, it's worth asking how they manage document collection and status updates once your case is filed, not just who signs the application.
How to tell a licensed specialist from an unlicensed agent
Quick answer: Ask directly whether they are a registered 行政書士 with a prefectural registration number, or whether the firm employs one — anyone actually authorized to file COE applications will answer this immediately and without hesitation.
Unlicensed "consultants" can still be useful for informal advice or referrals, but they cannot legally prepare or submit your COE application to Immigration. If a firm is vague about licensing when asked directly, that's a reasonable reason to keep looking rather than proceed.
Which contact path is closest to your situation?
Quick answer: If you're an individual applying from overseas, start with a 行政書士 or immigration firm and bring your passport nationality, target visa category, and sponsor details to the first call. If you're a company sponsoring a hire, expect to provide corporate registration and role documentation upfront. If your case has already been denied once, go to an immigration attorney, not a 行政書士, for the appeal.

FAQ
Can I file a COE application myself without a 行政書士? Yes — a sponsoring organization in Japan can self-file. In practice, most companies and individuals use a licensed specialist because filing errors are a common cause of delay, and the specialist absorbs that risk.
Is a COE the same as a visa? No. The COE is issued by Japan's Immigration Services Agency and confirms you meet the requirements for a status of residence. You then present it to your home country's Japanese embassy or consulate to receive the actual visa.
How long does the whole process take? COE review is typically 1–3 months depending on category and regional ISA office, plus embassy visa issuance afterward, which is usually faster. Startup Visa municipality review runs on its own separate timeline, generally 5–6 months.
Do embassies help with COE strategy? No — embassies process the visa stamp once you already hold an approved COE. They don't advise on visa category selection or file COE applications.
