Hello,
I'm a foreigner who lives in Taiwan, i'm familiar with Taiwanese immigration law and process. I can help you to reach your goal. For applying permanent residence in Taiwan, you need to get ARC(Alien Resident Card) first, , and than will be qualified for APRC(Alien Permanent Resident Card) after continuous 5 yrs residence in Taiwan. But in the case of investment immigration(invest US$500,000 for business in Taiwan, or buy $1 M government bond), only 3 yrs residence requirement.
I can help you to do paper work and schedule your agenda. I'm located in Kaohsiung City, can go to immigration in here also with your authorization for submitting, filing papers etc.
I'm looking forward to hearing from you soon.
Best regards,
Hui
