A “business visa for Taiwan” can mean a variety of things. There is a difference between doing business, starting a business and engaging in business activities in Taiwan. Visa information and application in Taiwan is opaque, confusing and rarely straight forward, especially as far as accessible information is concerned. Moreso now during COVID-19 pandemic times than ever before. Current information is basic at best and you should always double and triple check with the relevant authorities at the BOCA and NIA in Taiwan or your local TECO office abroad.
As a digital nomad or remote worker, there are multiple visa options in Taiwan during COVID-19. First, there is the option of applying for an entrepreneur visa, a visa that provides an initial one year residency permit and permission to work for oneself, developing business ideas and executing potential company, representative or branch office setup in Taiwan. Second, applying for the employment gold card, a three to five year residency and open work permit, primarily aimed at attracting high level talent and investment to Taiwan. Third, one can open a representative or branch office of a foreign company in Taiwan. Fourth, one can start and register a completely new company in Taiwan.
