Got my visa approved this week at Taipei, it was pretty smooth for me. I applied as a remote worker and I provided 6 months bank statements, employment contract, remote work agreement and a letter from the company. Tbh it seemed they were mainly interested in the bank statements.
I was a bit worried as I have only just started the job and haven't received a paycheck yet, but it all went fine.
There were a few others applying who seemed to get quite a grilling, but I think it may have been because they had more complex situations that the staff couldn't quite understand, but I believe everyone got approved in the end.
If you've got any questions, ask away. And thank you to this group, you've all been very helpful!
