<p>“I know a few foreign TAs who teach math/sciences. They are extremely aware that they have an accent (which embarrasses them) and that they may not be easily understood by their American undergraduate students (which horrifies them.) As result, they GO OUT OF THEIR WAY to work one-on-one with any student who requests it. They put an incredible amount of effort and time into their teaching work.”</p>
<p>That has been my experience too.</p>
