3 year ARC for my wife, how to get it upon entry?

Hi Forumosa Community,

My Wife and I are moving to Taiwan next month. She is Syrian and I am a Taiwanese Citizen and she is entering on a Visitor Visa. We would like to get her the 3 year ARC. Can someone tell me how we can maximize our chances of getting this? Is it possible for first time applicants?

Thanks in advance
