In order to hire a Foreign “White Collar” Worker, a Taiwanese Company must have at least a paid up capital of 5 Million NTD (NT$5,000,000) and must show yearly profits of at least 1 Million NTD (NT$1,000,000). Also, the company must pay the Foreign worker more than twice the minimum wage (not too sure of the figure but I think it was around NT$47,971) and justify why a foreign worker is needed to do the job which cannot otherwise be done by a local.
The potential employee must have at least a College Degree and 2 years of relevant work experience in the field of work in which he/she is getting hired into. You don’t need to show work experience if you hold a Masters Degree or PhD.
These were the requirements needed when my Company hired me more than ten years ago…it could have changed somewhat but I doubt there would be much difference. For a definitive answer, ask your would-be employer to call the Workforce Development Agency (or whichever agency that’s in charge of issuing Work Permits) like yyy suggested. After all, it is the responsibility of your Employer to find out what’s needed to hire you and not vice versa.
