I needed to legalize a couple of Thai-issued documents while I was outside of Thailand. Alpha Legal handled the job smoothly and very quickly which was also very importan for me as I had a limited timeframe. They promptly prepared the POA, received my documents by post, went to the embassy to legalize them in ONE DAY, and sent the legalized documents back to me. And also, 5⭐️ for communication – Veronica was ready to discuss all the aspects of the job over wasap at all times, even though we were on the opposite sides of the globe. I recommend Alpha Legal to everyone for a client-oriented service without hesitation!
