Factor

Typical cost

Use an agency

40,000–50,000 THB per application for a full‑service retirement visa package, including government fees.

Do it yourself with a system

Around 3,800 THB for a structured course or blueprint, plus the normal government fees you’d pay anyway.
What you're really paying for
Convenience, someone else dealing with forms, queues, and some bank/immigration interactions.
Clear instructions, checklists, and understanding of the rules so you can apply and renew yourself.

Time & effort

Less admin time, but you still supply documents, sign forms, and sometimes show up in person.
More hands‑on: you schedule visits, prepare your own file, and submit at immigration – but on your timeline.

Control & transparency

Lower: you may never fully see what’s being filed in your name or which rules are being “smoothed over.”
Higher: you know exactly how your visa works, which documents were used, and how to repeat it each year.
Long-term risk
If your agent uses workarounds or “special channels,” you may become dependent on them and find it harder to switch back to DIY later.
You stay within the published rules, build confidence with immigration, and can adapt as regulations change.

Who it suits

People with more money than time, very low tolerance for bureaucracy, or unusual edge‑case situations
People who can follow clear steps, want to save money long‑term, and prefer understanding their own visa.
