Clients in Udon Thani can walk in at Udon Thani Branch.
Udon Thani is the main city of the upper north-east, with an international airport and a large community of Thai–foreign families. The files we see most here are marriage documents, income or address confirmations for immigration filings, and powers of attorney for use abroad.
Our staffed office in Udon Thani also serves clients from Sakon Nakhon, Nong Bua Lam Phu and Loei who prefer not to travel to Bangkok. For anything that must go to an embassy, we check the whole set before it leaves the province, because a single missing page usually means a second long trip. Where a foreign authority wants an original rather than a copy, we tell you before you sign so the right number of originals is prepared.
Many Thai–foreign families in Udon Thani renew their visas every year, and the same supporting documents come back each time. Keep certified copies of the documents you reuse, and check the issue date of each one before filing, because immigration officers often want papers issued within a recent window rather than the copy from last year. We keep a checklist of what each family reused, so the next renewal starts from the correct, current set instead of from scratch. Bring your passport with every previous extension stamp, because officers compare the new file against the history it shows.
Northeastern Thailand has trade, service, agricultural and border-business networks. The filing plan should account for original-document logistics and authorities serving the actual premises.
Before filing in Udon Thani, confirm the Revenue Office responsible for the real address and appoint a premises contact for official correspondence or a factual inspection.
Company filings are handled by DBD, while VAT registration is handled by the Revenue Department office responsible for the Udon Thani premises. Names, addresses and signing authority must remain consistent across both filings.

The reserved name duplicates or resembles an existing entity
The registrar screens for identical and confusingly similar names as well as restricted words; submit several alternatives when reserving.
Objectives are too broad or cover licensed activities
Objectives naming activities that require a separate licence must be removed or evidenced with that licence; keep the objectives aligned to the real business.
Registered signing authority conflicts with how documents were signed
The authority clause — how many directors must sign jointly and whether the seal is affixed — must match how the application and every attachment were actually signed.
Foreign shareholder documents lack the required authentication
Passports or corporate documents issued abroad usually need notarization plus embassy authentication, together with a translation in the form the registrar requires.

In most cases no. Filings with central authorities such as the Department of Consular Affairs or an embassy can be handled on your behalf. Steps that legally require you in person — fingerprinting, or signing in front of the certifying attorney — cannot be delegated.
Turnaround depends on the responsible authority’s queue and rules at the time, so we publish no fixed figure. We tell you the authority’s own published window on the day you ask, plus the steps that usually cause delay.
Our team can review documents and coordinate translation, signature certification, legalisation and embassy steps within the agreed scope. Some steps may still require the document owner to appear or sign in person under the receiving authority’s rules.
We do not publish fixed prices: official fees, page counts and language pairs differ in every case. Send the document details and destination and we will scope the work and cost for your specific case.
Documents can travel by trackable EMS or private courier. Confirm the recipient, address and original-document handling before dispatch; the coordinating destination is Udon Thani Branch.
Send the document details and the destination that will receive it. We map the correct chain before starting, flag what usually gets rejected, and run it end to end — as advisers, not just a filing agent.
