I had it for 10 years no probs ..just make sure you have the 800 k in bank there is another way to get it that's through a agen .no need for money in bank but it's costs you aprox 25 / 30 k for agent to do it ..it's all legit but you don't have to do any think just give passport to agent they do it all ..
You can do it with agent ..it's aprox 30k but you don't need money in bank at all .. but you need a 60 / 90 day visa first ..I always done it myself. But many I know use a agent costs more but it's easy
Why bother going at this time it could all be in vain if you are positive when land in Thailand. Then of to hospital for 10 days ....I lived there for over 10 years great place to live but untill all this nonsense is over I'll wait to get back ....
