Staff Members Praised by Name

When clients consistently name eight different staff members across their reviews, you're not looking at a visa agency — you're looking at an institution. Siam Legal has spent 20 years building something rare in Bangkok's visa services landscape: a full-service international law firm that handles everything from DTV visas to US immigration, property law to marriage services, all while maintaining a 97% user score across 1,638 reviews.

  • Scale meets quality — 51-200 employees, yet 94% of all reviews are 'very positive'. Size hasn't diluted their service.
  • DTV visa dominance — The most-mentioned visa type in their reviews, with clients praising the speed and clarity of the process.
  • International scope — Beyond Thai immigration: US visas, European visas, LTR, Thailand Privilege. A true one-stop legal firm.
  • Named staff across departments — Kanda (DTV), Ploy (Workation), Belle (Privilege), Rex & Jess (Elite), Linda (US visas), Ping (LTR), Tan (Marriage) — clients don't just praise the firm, they praise individuals.
  • Inclusive services — Explicitly praised by LGBTQ+ couples for professional, respectful marriage assistance.
