Thank you for your input AuroraB, and I appreciate your suggestion. However, I believe that forms may be better suited for quantitative research, whereas my study focuses on exploring opinions and experiences qualitatively. Therefore, meeting in person and recording their opinions would be more beneficial for my research. I understand the importance of privacy, and I can assure you that I will use code names to protect the identities of the expats who wish to remain anonymous. Alternatively, they can introduce themselves using a code name. What are your thoughts on this approach?
I guess you will find most expats within the tourist zones, although quite a few are already integrated into local residential areas. In Sanur there are a big crowd living west of Jl. Bypass inside local residential zone. Apart from hotels, villas and bars you will find expats at the major supermarkets like Grand Lucky.
If you check through posts within this (open) forum using the keywords you are interested in like "hospitals" or "health", "villa" etc. you will get an idea.
There are probably other forums or social media that could be relevant.
