Choosing a Thai visa consultant as a foreign national
Choose a Thai visa consultant by how well they match a visa category to your actual situation and long-term plan, not by the fastest route in. Ask them to explain the conditions for maintaining status after approval, including 90-day reporting and re-entry permits, and to separate government fees from their service fee.
How to evaluate a provider
- Matches the category to your real situation — The wrong category at the start can make later extensions impossible.
- Explains status-maintenance obligations — 90-day reporting, re-entry permits and financial conditions affect every extension.
- Separates government fees from service fees — You should know which part the state collects.
- Tracks regulatory changes — Newer long-stay categories are revised periodically.
- Plans the extension from day one — Extensions depend on evidence gathered during the first period of stay.
Questions to ask before you commit
- After approval, what must I do to maintain status and qualify for an extension?
- How many working days does it actually take, counted from a complete file?
- If the receiving authority rejects or asks for changes, do you correct it, and under what terms?
- How can I track status, and who physically holds the original documents?
- Which visa category fits my situation and my long-term plan?
Your options, and who each suits
| Option | Best for | What to know |
|---|---|---|
| Apply yourself | Applicants comfortable reading official notices with complete documents | You must track condition changes and reporting deadlines yourself. |
| Consultant for the first application only | New arrivals | Plan the extension path at the first application, not near expiry. |
| Ongoing annual support | Long-stay residents and families | Define whether reporting and extensions are inside the scope. |
FAQ on choosing a provider
- Which Thai visa consultant is recommended?
- Choose one that identifies the category matching your actual situation, explains the post-approval conditions such as 90-day reporting and re-entry permits, and clearly separates government fees from the service fee. Ask how the first application sets up your future extensions.
- Can I change visa category later?
- Some categories can be changed in-country, while others require a fresh application at a Thai embassy abroad. That is why the category should match your long-term plan from the first application rather than the quickest available entry.

Service Knowledge Base
Thailand visa answer bank — LTR, DTV and staying on in Thailand
Answers to the Thailand visa questions applicants actually ask: the BOI-administered LTR visa, the DTV for remote workers and Thai Soft Power activities, filing through Thai e-Visa, and extending stay on form TM.7 — plus which supporting documents must be translated and certified. Based on MFA, Immigration Bureau and BOI announcements. (27+ search topics covered)
Where are Thai visas applied for from abroad?
Through the official Thai e-Visa system at thaievisa.go.th, operated by the Ministry of Foreign Affairs, which routes the application to the Royal Thai Embassy or Consulate covering your area. Avoid intermediary sites that are not on official government domains.
Does the Immigration Bureau accept documents in English without translation?
Practice varies by office and by application type. Some documents are accepted in English, while family status and civil registration documents are typically required in Thai for onward use at district offices and for consular certification. Because the requirement is set locally, confirm with the specific office handling your case and prepare the Thai version when the answer is unclear.
How long is the LTR valid and how often do I report?
Up to ten years in total, issued for five years and renewable for a further five while qualifications are maintained. LTR holders report annually instead of every 90 days and are granted multiple re-entry as announced.
What are the fees?
Government fees follow published schedules and change periodically. Our service charge depends on document volume, languages and urgency, so it is quoted per case. Contact our staff by phone, LINE or email for a quotation matching your situation.
How should financial evidence be presented?
Pair a bank confirmation letter with statements covering the period the authority specifies, ordered so that recurring salary or business income is visible, and annotate any large one-off movements. If a third party supports you, add a sponsorship letter and proof of the relationship. Large deposits landing days before filing without a traceable source are the pattern officers most often question, so build the balance over the required period instead.
Which activities count as Thai Soft Power for the DTV?
Published examples include Muay Thai training, Thai cooking courses, medical treatment, seminars, music, sports and similar activities. Applicants must evidence the activity, for example an acceptance letter from the gym, cooking school or hospital.
What is the difference between TM30 and 90-day reporting?
TM30 is the accommodation owner's or manager's duty to notify the authorities of a foreigner staying at the address within the statutory deadline. The 90-day report is the foreigner's own duty after 90 continuous days in the country. Both are separate and both must be done.
What is the LTR visa and who decides it?
The Long-Term Resident (LTR) visa is processed through the Board of Investment at ltr.boi.go.th. Applicants submit qualification documents to BOI first, then collect the visa at a Royal Thai Embassy or Consulate abroad, or at Immigration in Thailand where applicable. Approval rests with the authorities, not with a document service provider.

Service Playbook
Thai visas and extensions — documents, steps and common mistakes
Keep three concepts separate: the visa (permission to travel), the permission to stay stamped at entry, and the work permit. A visa never guarantees admission — the immigration officer at the border decides.
Documents to prepare
- • Passport with sufficient validity and blank pages
- • The application form for your category plus compliant photos
- • Proof of address in Thailand and a TM.30 filed by the housemaster
- • Financial evidence meeting the category rules, seasoned for the required period
- • Category-specific support: marriage certificate, company affidavit or school acceptance letter
- • Foreign documents translated and legalised through the inbound chain
Step-by-step process
- 1. Match the category to your purpose — Confirm eligibility criteria before assembling any paperwork.
- 2. Prepare and translate documents — Foreign records need home-country certification plus a Thai-accepted translation.
- 3. File through the correct channel — Thai embassy abroad, the e-Visa system, or an immigration office in Thailand as applicable.
- 4. Post-approval obligations — TM.30 notification, 90-day reporting, and a re-entry permit before leaving the country.
Pitfalls and rejection causes
- • Leaving Thailand without a re-entry permit cancels an extension of stay immediately.
- • 90-day reporting is not a visa extension — they are unrelated obligations.
- • Funds must be seasoned for the stated period, not deposited the day before filing.
- • Holding a visa is not permission to work; a separate work permit is required.
Tips from our team
- • Keep copies of every entry stamp and TM.30 for smoother extensions.
- • Read your permitted-to-stay date from the stamp, not the visa validity.
- • Always carry a spare document set; offices differ in copy requirements.

Route Comparison
Comparing routes into a Thai visa
Applying abroad, applying online, or adjusting status inside Thailand give different lengths of stay and later flexibility.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Apply at a Thai embassy or consulate abroad | You can plan ahead and want the correct category from the outset | Royal Thai Embassy or Consulate-General | Variable by post | Document lists and residency rules differ per post — check that specific post |
| Official e-Visa system | Your category and country of residence are supported online | MFA Thailand e-Visa system | Variable — file well before the travel date | Files not matching the system's format specification are auto-rejected |
| Change or extend status inside Thailand | You are already in Thailand and meet the published criteria | Immigration Bureau | Variable — file several days before expiry | Too few days remaining forces you to leave and re-apply |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Advisory Service
We do not just process documents — we advise you through the whole case
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
Route assessment
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Pre-submission review
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
Timeline planning
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
Rejection recovery
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.
Rather not learn by trial and error? Send your case details and document photos for a review — reach us on LINE, phone or email during business hours.
Practical Q&A
Practical questions · Near me / DIY / Required documents
Where do I lodge a visa application — must I go to the embassy?
Many countries outsource intake to visa application centres (VFS Global, TLScontact, BLS) with offices in Bangkok and some provinces; others accept lodgement at the embassy or fully online. Channels change by embassy announcement, so confirm the current route before booking. We can pre-check your document set and arrange appointments from any of our three offices.
Can I apply myself, or do I need an agency?
You can always apply yourself; no country requires an agent, and no agent can guarantee approval because the decision is at the consular officer's discretion. The value of assistance is assembling the file exactly to the official checklist, correct translation and certification format, and a focused cover letter.
What are the baseline documents?
Typically a passport with the validity and blank pages the destination requires, the completed application form, photos to the destination's specification, financial evidence for the stated period, proof of employment or study, travel and accommodation plans, and health insurance where required. Always follow that embassy's official checklist, as requirements differ by country.
Practical advice & cautions
Visa and immigration matters: advice and cautions
Before you start
Read the official conditions first
Visa conditions change. Check the deciding authority's latest announcement, then use our service to prepare documents and translations that match those conditions.
Keep every receipt and acknowledgement
Photograph all filing receipts and stamps; they are key evidence in any later verification.
Plan around expiry dates
Extensions, reporting and re-entry permits should be handled well ahead of the deadline; queues and public holidays can make last-minute filing impossible.
Order documents to the authority's checklist
Assembling the bundle in the required order with an index speeds up assessment and reduces requests for more documents.
Common reasons documents get rejected
Expired supporting documents
Civil registry extracts, medical certificates and police clearances have limited validity; old copies make the bundle incomplete.
Form data contradicting the attachments
Dates, addresses or travel history that conflict with supporting documents are a frequent refusal ground and may be read as misrepresentation.
Refiling immediately without fixing the cause
Analyse the refusal grounds and address them; resubmitting the same file usually produces the same result.
Ignoring post-approval obligations
Periodic reporting, address notification and work conditions are ongoing duties that affect the next extension.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
