I'm from the United States and I'm thinking of coming to work for a friend company in Chiangrai and Chiangmai in January. What type of visa do I apply for and how long will the visa last? I also want to know what is required to get that visa. Thanks in advance.
TLDR : Answer Summary
To work in Chiangrai and Chiangmai, you will need a 90-day Non-Immigrant Type B visa, which is specifically for business purposes. You should consult with the company you will be working for, as they will provide important information regarding your visa. Additionally, check the Thai consulate's website in the US for specific requirements for applying, as these may vary by location. After the initial 90 days, you can apply for a yearly extension at the immigration office with documentation from your employer.
