lately they do the visits for most visas even when single or farang couple to make sure your not doing business in your condo or house and if you really live there.
now you are scaring me 😟 We had help from an accountant for the first extension (based on non-O retirement visa) last year just to save time, but we had all the necessary docs and met the requirements we could open bank account and immediately transferred the required 800k from our foreign account, we had to make a CoR, pictures of house, map showing where we live and went to the bank ourselves to collect statememt and letter. The agency just saved us a lot of time by collecting all our docs and passport and went to IO and 2 days later we had our EoS mult. entry. After several months we now know exactly what it needs and now we have more time to prepare. We will try next extension ourselves, why shouldn‘t this work for us without an agent?
