How we work together
You fill in a short questionnaire and hand over the basics of your case.
We assess the risk — past stamps, refusals, overstays — build the filing strategy and fix the final price with no hidden charges.
You collect the documents from our checklist — bank statement, certificates, photo, bookings.
We audit the documents: statement format, translations, dates, wording. You get corrections back.
You complete the e-Visa form under our supervision and pay the consular fee.
We run the process, track the status and help you answer any follow-up request from the consulate.
You enter Thailand.
We check the issued visa for consulate errors and give you border-crossing instructions.
FAQ
Can I extend on Koh Phangan or Koh Tao?
Koh Phangan and Koh Tao fall under different immigration jurisdictions. Check which office covers your location.
Is the process the same as Bangkok?
The forms and fees are the same. Smaller offices may be faster but less flexible with edge cases.
