Practical playbook: Thai Visas and Work Permits

Working or staying long term in Thailand means matching the correct visa category to your activity, then keeping visa, work permit and reporting obligations aligned throughout the stay.

Documents to prepare

Passport valid well beyond the intended stay
Employment contract or invitation letter from the Thai entity
Company documents (DBD affidavit, shareholder list, financial statements)
Education and professional credentials, translated and legalised where required
Proof of funds or income as required by the category

Steps and method

1. Category assessment
Match the intended activity to the correct visa class before any document is prepared.
Typical timeframe: 1–3 days
2. Document preparation
Collect, translate and legalise credentials and corporate documents to the current checklist.
Typical timeframe: 5–15 business days
3. Visa application
File at a Thai embassy or consulate, or apply through the e-Visa system where available.
Typical timeframe: 5–20 business days
4. Work permit and reporting
File the work permit with the Department of Employment and keep 90-day reporting and address notifications current.
Typical timeframe: 5–10 business days

Consultant tips

Confirm the employer's ratio and capital requirements before promising a start date.
Keep digital copies of every entry stamp, extension and receipt.

Pitfalls to avoid

Working on a tourist entry is an immigration offence with lasting consequences.
Missing 90-day reporting or a change-of-address notification creates fines and complicates extensions.

If you would rather not handle the paperwork yourself, the iVC team can run the whole file end to end — document review, translation, certification, submission and follow-up. Contact us by LINE @iVisa or call +66 80-557-8887 so we can assess your case before any work starts.

Thai long-stay and work routes compared

Choose by the nature of your income and employer, not only by duration.

Aspect	Non-B + work permit	DTV	LTR
Best for	Employment with a Thai employer	Remote work for overseas employers or clients	Applicants meeting a BOI-defined category
Thai employer required	Yes	No	Depends on the category
Work permit	Required	Does not cover working for a Thai business	Category-specific channel
Core documents	Employer company documents plus qualifications	Evidence of remote work or the qualifying activity	Evidence for the chosen category

Doing it yourself vs having iVC manage the whole process

Both routes are valid. They differ in the time you spend, the risk of documents being returned, and whether an adviser reviews everything before submission.

Aspect	Do it yourself	Managed by iVC
Pre-submission review	You check against the agency's published requirements	An adviser checks each document against the destination's rules first
Your time	You travel, queue and follow up yourself	We file and follow up; you receive progress updates
Rejection risk	Common causes: name spelling mismatch, expired documents, wrong certification order	We check the usual rejection triggers at source and fix them first
Specialist knowledge	You research each agency's rules yourself	A team with 15+ years of casework advises throughout
If something goes wrong	You restart the steps yourself	We assess the options and plan the fix immediately

We work as advisers, not just a document courier

More than 15 years of casework (since 2011) in translation, certification and visa document preparation shows us the patterns behind repeated rejections, so we plan around them from the start.

Case assessment first: We review the profile, destination country and receiving authority before recommending a certification route.
A document plan per person: We sequence what must be re-issued, translated first, and certified in which order.
Risks flagged early: We point out the usual rejection triggers, such as name spelling that differs from the passport or document age limits.
Follow-through to the end: Regular progress updates, and immediate options if the authority requests more documents.
Advice after completion: The same set is often reused in the next step; we check whether it still qualifies or needs re-issuing.

If you would rather not chase each step yourself, send the case details for an assessment first, then decide.
