<p>You have to search "Child Labor Law" of your state to find information not only about occupations but also about hours allowed to work.</p>
<p>For example Texas Child labor law <a href="http://www.twc.state.tx.us/ui/lablaw/cllsum.html%5B/url%5D">http://www.twc.state.tx.us/ui/lablaw/cllsum.html</a></p>
<p>Both permitted and prohibited occupations are listed.</p>
<p>New Jersey child Labor law <a href="http://www.state.nj.us/labor/lsse/lschild.html%5B/url%5D">http://www.state.nj.us/labor/lsse/lschild.html</a></p>
<p>If you are told in NJ that you cannot be hired at the grocery store show them the law and promise problems with the government for discrimination.</p>
