thanks for your post! If you have your own business in the States, do you know if there is any problem writing your own letter explaining that you’re self employed and the owner of the company,…obviously with detailed description of your company‘s business.? Thanks in advance! 🙏
If you have a trusted friend or family member in the US that wouldn’t mind sending receiving OTP or calls, you could always ask them and change your bank profile to their phone number. That’s always an option.
that’s exactly what I have….you are 💯 correct. I didn’t realize the poster was talking about a different kind of visa. Sorry for convoluting the post. 
I recently went to Phuket immigration on same type of visa and the officer told me that every time I leave the country and come back I would get a new stamp for 90 days…and he said in the situation where I was planning to leave back for my home country (USA) a few days after the 1 year expiration of the visa, he told me just leave Thailand and come back before it expired and I’ll have an additional 90 days and would not have any issues departing after 1 year expiration date.
