Looked a bit into gold card recently. Do you currently have it and are you working remotely?
I've been studying Mandarin here for a while after being a software engineer for a few years. Been thinking about what I'm gonna do once I feel comfortable in the language. Working remotely would be great if I could pull it off.
The other way is to qualify for any of their "talent" needs. Blockchain, VR, IA, and have proof it it (publication, work, projects). They have 8 categories of people that can qualify: https://foreigntalentact.ndc.gov.tw/en/cp.aspx?n=128B875DE9C...
Just keeping my options open at the moment.
