Thai immigration paperwork — questions foreigners actually ask

Answers on documents supporting Thai immigration matters — extension of stay (TM.7), address notification (TM.30), 90-day reporting (TM.47) — and how supporting papers should be translated and certified, based on the Immigration Act B.E. 2522 and Immigration Bureau notifications. (24+ search topics covered)

Do foreign documents filed with immigration need translation?

Documents not in Thai or English normally need an accompanying translation, and officers frequently require the certification chain applicable to your nationality — your embassy in Thailand and/or MFA legalisation — before acceptance.

How are foreign degrees certified for a work permit?

Generally they are certified in the issuing country and legalised by the Royal Thai Embassy there, or attested by that country's embassy in Thailand and then legalised by the MFA, with a Thai translation attached. The exact chain depends on the issuing country.

Can an overstay be undone?

No. Overstay carries fines and can trigger statutory re-entry bans. We cannot remove those consequences, but we can prepare supporting documents and assist with contacting the authority through the correct procedure.

What is a TM.30 and who is responsible for filing it?

TM.30 is the notification of a foreigner's place of stay, filed under the Immigration Act by the house owner, possessor or manager of the property — in practice the landlord, condominium juristic person or hotel. Immigration offices frequently ask for the TM.30 receipt when processing extensions or 90-day reports, so tenants should obtain a copy at move-in rather than at the counter.

What happens if a 90-day report is filed late?

Late filing is generally handled as a reportable irregularity and a fine may be assessed at the counter under Immigration's discretion; the report is then accepted and the cycle restarts. It does not automatically invalidate the permission to stay, but a pattern of late filings can attract additional scrutiny during an extension. Keep every receipt, since officers may ask for the previous one.

What happens to visas and stamps when a passport is renewed?

Bring both the expired and the new passport to Immigration so the permission-to-stay stamps can be transferred to the new book under current practice, together with copies of both data pages and any documents the office requires. Until the transfer is completed, carry both passports when entering or leaving the country, since officers need to see the earlier stamps. Also update the passport details in your reporting and address-notification records so all systems match.

What is TM.30 and who must file it?

It is the notification of a foreign national's residence. The duty falls on the house master, property owner or hotel manager — not the foreigner — and can be filed at the immigration office, by post, or through the online channel the Bureau publishes.

Can you file on my behalf?

Some steps, such as TM.30 and 90-day reporting, allow an authorised representative or postal/online filing. Extension applications and interviews usually require the applicant in person. We confirm the rule at your assigned office before booking.

Thai immigration compliance — TM.30, 90-day reports and re-entry

TM.30 address notification is the housemaster's duty; the 90-day report (TM.47) is the resident's. Neither is a visa extension.

Documents to prepare

  • • Passport with the current entry stamp and departure card
  • • Proof of address such as a lease or a housemaster letter
  • • The housemaster's house registration and ID for TM.30
  • • Your previous receipt for the next 90-day report
  • • Re-entry permit application if you plan to travel
  • • Power of attorney if someone files for you

Step-by-step process

  1. 1. File TM.30 on arrival at the address — The housemaster or landlord files within the statutory window.
  2. 2. Report at 90 days — In person, by post or online within the permitted window.
  3. 3. Obtain a re-entry permit before leaving — Single or multiple, depending on your travel plans.
  4. 4. Keep every receipt — Receipts support your next extension filing.

Pitfalls and rejection causes

  • • Leaving without a re-entry permit ends your permission to stay.
  • • A missing TM.30 can stall an extension.
  • • The 90-day report has a fixed window — diarise it.
  • • Overstay carries fines and future travel consequences.

Tips from our team

  • • Set a reminder seven days before each deadline.
  • • Photograph the entry stamp and every receipt.
  • • File a new TM.30 whenever you move.

Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.

Route Comparison

Comparing Thai immigration routes

Extending, changing visa category in-country, or leaving to re-apply abroad carry very different timelines and risks.

RouteWhen to useCertifying authorityApprox. durationRejection risk
Extension of stay at an immigration officeYou are still within your permitted stay and meet the criteriaImmigration BureauVariable — some offices decide same-day, others place the case under considerationFiling on the last permitted day leaves no room to fix documents if more are requested
Change of visa category in-countryYour purpose of stay changed, e.g. tourism to employment or familyImmigration Bureau, under the published criteriaVariable — allow time for additional document requestsToo few days remaining under the criteria forces a fresh application from abroad
Apply for a new visa at a Thai embassy or consulate abroadThe category cannot be changed in-country, or the profile suits an overseas filing betterRoyal Thai Embassy or Consulate-General abroadVariable by postEach post sets its own document list and residency conditions — verify before travelling

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

Is there a service point near me?

Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani. We serve the whole country through scans and document courier, and can meet at city rail stations or malls. Ask our team by phone, LINE or email for the most convenient option.

Can I handle this myself?

Many steps can be done personally under the relevant authority's rules. What usually costs time is the wrong sequence, a translation format that does not match the requirement, or a source document version the recipient will not accept. Check the destination checklist before starting and ask us if anything is unclear.

Which documents should I prepare?

Generally the original document from the competent authority, the owner's ID or passport, a translation in the format the destination requires, and a power of attorney if someone acts for you. Details vary by service type — ask our team for a case-specific checklist.
Practical advice & cautions

Visa and immigration matters: advice and cautions

Before you start

  • Check passport validity and blank pages

    Many countries set a minimum remaining validity and number of blank pages. Verify before your appointment.

  • 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.

  • 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.

  • Ignoring post-approval obligations

    Periodic reporting, address notification and work conditions are ongoing duties that affect the next extension.

  • Refiling immediately without fixing the cause

    Analyse the refusal grounds and address them; resubmitting the same file usually produces the same result.

  • Believing guaranteed-approval claims

    No provider can guarantee an outcome; only the immigration authority or embassy decides. Our role is to make the file accurate and complete so avoidable rejections are reduced.

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.
