Exactly. If she's Filipino, Indonesian or any other South eastern nationality, that does not limit her only to a blue collar job. She might be telling the truth regarding having a white collar job.
However, as Bumclouds points out, the math does not add up. Even if she is -probably, I presume- listed as Overseas Chinese, as many of South East Asia white collar workers I know, fellow students or editors or finance people.
OTOH, Bumclouds, there is just so much you can do. Your spidey senses are telling you something is afoot, but if the affected party -your friend- cannot or doesn't want to see it, then, aside from speaking your piece -which will not be well received- there is little you can do. In matters of the heart, the worst blindness comes from the one who shuts his eyes, as we say in Spanish.

If any new arrival needs assistance in Taipei, I can provide it in exchange for Star Trek or Supernatural
(the TV series) stuff or other sci-fi materials. Let me know what help you need by PM, along with what you have to offer in return. And yes, I am serious.
