still good to use a company, I arrived 14th November on non o visa , lady helped me open a bank account, put my money in, and already stamped in extension until Feb 2027, easy peasy, saves the stress.
I used a company to get me a bank account and extension of my non o visa, no waiting in queues, well worth it for not having the hassle of misunderstanding.
I have done my non o in the UK and they have asked for insurance too, I thought it was just non OA, but Thai embassy in London asked me to provide health insurance, as it was I have taken it out to start on our arrival date, but they definitely are asking for it, my application has anyway.
