Was I biased in determining eligibility?

I think requiring the eligibility papers is a valid thing. And since the worker agreed that she will be paid only after the certifications were produced, no one can accuse you of not being fair in this situation. However, for humanitarian reason, if the teacher finished her assigned work and did well, it is still best if you had paid her. Well, if her work will be deemed void without the credentials you are requiring, then that's another story.

If you allowed this woman to work for you without showing you her credentials because she looked and sounded American I would probably say that while you're not a racist you're unfairly judgmental of people who don't look and/or sound American - or maybe too lax in making sure people who do look and/or sound American have the right credentials.

The majority of the people in the world are from other countries, so isn't it kind of weird that so many of us think that people from our country are better than others?*grins*

This time i am really confused, how or what do you base on a person to say she sounded or looked American? Is it by English language with heavy Yankee accent or one with hook noose or blue eye ball or kinky hair, i am at a total loss at how is that possible to define who is the real American.
