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.
