The "normal" thing here is that your name match on your AIS and Bankok bank are different or the AIS account has not been verified. Just take your documents into your branch and they should release it. By the way do you go into your local bank regularly?
I can't offer tax advice, but I saw recently that YouTubers in Thailand have been told they should pay tax, in their case they are making content of Thailand. If your work is totally un-connected to Thailand its different. But dont forget money remitted to you from outside Thailand is very like taxable.
I think its 15, but a parent can open an account on behalf of a child under that age, but the parent is responsible. I'm not sure if the child can use all the facilities, like debit card, probably not.
outside of Bangkok private school will be cheaper, I pay 60kthb school fees a year. Its a Thai private school, but a young person should pick the language quickly.
indeed, but i just recently got a second sim, in my name and with my passport, I called AIS about something and I asked about the second sim they said "its in your name" but not verified, you need to go to AIS and have if processed with your passport" I think there are two processes.
Your fiancé's K-1 visa interview at the US Embassy in Bangkok will focus primarily on verifying the legitimacy of your relationship and your fiancé's eligibility for the visa. Typical questions asked recently in these interviews include:
About the Thai fiancé(e):
Personal details such as full name, nationality, birthday, age, education, languages spoken
Previous travel history, especially visits to the US
Past marriages or children
Employment and background details
Any criminal history
About the US fiancé(e):
Information about you (the petitioner), including your life, work, and background
About your relationship:
How and where you met
Dating history
Future plans together to confirm the authenticity of your relationship
About the planned wedding and marriage:
When and where the wedding will take place
Wedding reception plans and guest list
Any pre-marriage celebrations
Honeymoon plans
Assurance that you will marry within 90 days of entry to the US
Your fiancé should be prepared to answer these questions truthfully and confidently. The interview typically lasts 20-30 minutes, with around 10-20 questions. The American fiancé (you) cannot attend the interview, but sometimes an attorney may accompany the applicant for support.
It's important your fiancé brings all required documents, attends a medical exam prior to the interview, and arrives on time at the embassy. The US Embassy in Bangkok usually processes K-1 visa approvals within about a week after a successful interview.
