Is your pension below the required level, or have funds not been held long enough? We help assess how to meet retirement or marriage financial conditions, or explore another eligible route.
No residence notification, missing documents or a deadline approaching? Contact us now. We will review what can be corrected and the steps you need.
We check your status and deadlines, explain eligible grounds, help prepare documents and support the agreed process. Start with your permission-to-stay expiry date and the problem you need to solve.
02 / PROBLEMS WE HELP WITH
Find a situation like yours. Open the card for general requirements and the help we can provide.
Extension eligibility depends on your stamp, nationality and grounds. Thai authorities decide visas and permission to stay.
How we help
We check your stamp and previous extensions and prepare the package for an available in-country extension. If you have already extended, we assess any other eligible grounds.
Assistance from ฿3,000
General requirements and documents
A tourist visa normally permits up to 60 days with a possible 30-day extension. Visa-exempt entry is a different basis: your actual stamp matters. Another ordinary extension after one already used is not guaranteed.
Discuss this situation →How we help
We assess acceptable evidence of funds and income, the application sequence and deadlines. If you do not currently hold the balance, start with a review of eligible options.
Assistance from ฿14,000
General requirements and documents
Up to 15 months means a possible 90-day Non-O stage and a one-year extension if eligible. O-A and O-X are separate categories with different conditions, including insurance where applicable.
Discuss this situation →How we help
We review the family basis, financial documents and evidence of living together, and explain corrections needed before submission.
General requirements and documents
The ฿400,000 figure applies to a particular marriage basis, not every family visa. Children, dependants and other family circumstances have different conditions.
Discuss this situation →How we help
We check whether TM30 exists and help prepare or correct it with the person responsible for the property, including late-reporting steps.
General requirements and documents
The house-master, owner, lawful possessor or hotel manager has the notification duty, normally within 24 hours of arrival at the residence. Late reporting may involve a fine. TM30 is a notification, not a visa.
Discuss this situation →How we help
We check the employer’s package, identify missing documents and coordinate preparation to reduce delays from repeated requests.
General requirements and documents
A visa and Work Permit are different documents. We assist with preparation and coordination; expedited official approval is not promised.
Discuss this situation →How we help
We help identify a suitable programme and check school permissions, enrolment evidence and documents for that education basis.
General requirements and documents
Extensions depend on the programme and immigration’s decision. Attendance and compliance matter; protection against status cancellation cannot be guaranteed.
Discuss this situation →How we help
We check your stamp deadline and eligibility for a first extension. If it has been used, we review next steps and whether departure is required.
General requirements and documents
Each entry allows up to 180 days plus one extension of up to 180 days. Departure is required at the end of the maximum stay under that route. Any different basis for remaining needs separate assessment.
Discuss this situation →How we help
We help compare available programmes with your plans and prepare the application, including the difference between membership validity and your stay stamp.
General requirements and documents
Current packages and fees are checked before payment. Membership itself does not replace permission to work.
Discuss this situation →03 / FAQ
An in-country extension is available in many tourist cases. We first check your entry basis, latest stamp and extensions already used. If the ordinary extension has been exhausted, another ground needs a separate assessment.
Contact us now and give your permission-to-stay expiry date. We will check the documents and available application process. Contacting an agent does not extend your stay; do not wait for an overstay.
Yes, starting with your available funds, income and documents. We help assess acceptable financial evidence or another eligible basis. Approval without meeting the applicable conditions is not promised.
It is a possible sequence: an initial 90-day Non-O stay followed by a one-year extension. Eligibility depends on age, current status, deadlines and requirements. It is not a separate visa with an unconditional 15-month stay.
Yes. We help check the notification and prepare information with the property owner or manager. Late reporting may require correction and a fine. TM30 does not extend your permission to stay.
The standard DTV route permits one extension of up to 180 days per entry. After 180 + 180 days, departure is required under that route. If you want to remain, we separately assess whether another eligible basis exists; we do not promise a second extension of the same entry.
We help check the employer’s package early and coordinate preparation to reduce delays caused by errors. The competent authority controls official processing times and the decision.
Yes. We help identify a suitable school and check documents for the chosen programme. The education basis requires genuine study and compliance with its conditions; choosing a school alone does not guarantee the status remains valid.
Tourist-stay extension assistance starts at ฿3,000. Retirement assistance starts at ฿14,000. Even if you do not currently hold the required bank balance, you can start with an assessment. We agree the total price and included costs before work begins.

Your enquiry is handled by SiamDom Ltd. Read how we use, protect and retain your information.
SiamDom Ltd., 818 Supalai Condo, Theprasit Road, Pattaya, Bang Lamung, Thailand, operates this visa enquiry page and is responsible for the personal data described here. For privacy requests, contact us through Telegram @siamdom or call (English) / (Russian). Please identify your enquiry and request; do not send identity documents unless needed for proportionate identity verification.
The required fields are your name, a contact method and your consent. Other information is optional: citizenship, age, passport expiry, current and desired visa, extension count, last entry date, comments and a visa-stamp image or PDF. Our hosting and form systems may also process IP addresses, request times and technical security logs. Please send only information needed for your enquiry. Do not upload bank-card data, medical records or full passport scans here.
We use your enquiry to assess your situation, respond and discuss visa-assistance services you request. Your checkbox records consent to process information you voluntarily submit for this purpose. Where applicable, necessary steps at your request before a service agreement, performance of an agreement, legal obligations and legitimate interests in fraud prevention and security may provide other legal grounds. This checkbox does not sign you up for advertising. Publishing a customer review requires separate permission.
Enquiries are stored through the parent site’s WordPress/Forminator system. Access is limited to authorised SiamDom staff and service providers that need it for hosting, email delivery, maintenance or security. If you engage us for a visa service, relevant documents may be provided to authorised service partners and Thai embassies, consulates or immigration authorities as necessary for the agreed service and applicable law. We do not sell enquiry data. Messenger providers process messages under their own policies when you choose to contact us there.
Hosting, email or messenger providers may process information outside Thailand. Where transfers are subject to legal safeguards, appropriate measures must apply. An enquiry is not blanket permission to transfer sensitive information. Further document sharing for an agreed service will be explained separately.
For enquiries that do not become an active service, our retention policy is to delete or anonymise enquiry records and attachments within 90 days of the last substantive contact. For completed services, routine service records are retained for up to 12 months after completion. Records needed for tax, accounting, legal obligations or a dispute may be kept longer for the applicable period. Deletion includes relevant working copies and email attachments; backups may remain until their normal secure rotation. Security and rate-limit records are kept only as long as necessary for protection and incident handling.
Subject to applicable law, you may request access or a copy, correction, deletion, restriction, portability, or object to processing. You may withdraw consent at any time using the contacts above; this does not affect processing already lawfully performed. Some records may need to be retained for legal reasons. Refusing optional fields does not prevent an initial enquiry; without a name and contact method we may be unable to respond. You may raise a complaint with Thailand’s Personal Data Protection Committee (PDPC).
